We were asked to make a knife sheath and adjustable belt for workers in fish canneries. They needed to be rugged, inexpensive and easy to use.
The sheath is made from our 2″ #673 webbing which is extremely stiff and in commonly used for scuba divers weight belts. A pair of rivets and a bit of sewing and you have a functional sheath.
Every sheath needs a belt and this one needed to be adjustable and easily worn over cannery aprons or waterproof rain gear.
Here we used heavyweight #560 polypropylene webbing in an 1½” width. There are a few inches of elastic webbing to keep it taught without being uncomfortable and a side release buckle to make it easy to put on and take off. Finally a slide keeps the tail end of the belt secure and makes sure it doesn’t decide to loosen on its own accord.
Like the sheath there is minimal labor in producing the belt, helping keep the cost down. Is this something to wear around town? No, but it does fulfill the need if you are working in a cannery.
Most of your orders for webbing and buckles have been shipped out using Priority Mail. This has proven to be an inexpensive and reliable way to get goods to our customers. At times we receive orders that are so small that the minimum charge for Priority Mail is larger than the cost of the goods. We have been shipping these orders using First Class Mail which generally saves you, the customer, a couple of dollars.
We are working on providing that option for all orders that weigh less than 16 ounces. This requires that our shopping cart is able to calculate the weight of your order and then serving up the appropriate shipping options with their costs. Most of our components have been weighed and entered in to a database. Code is being written to do the calculations but it still needs to undergo testing. Our hope is to have this up and running by the end of March.
In the interim, if you are ordering a couple of buckles and want them to ship First Class Mail, let us know in the comments section. We try to keep your shipping costs as low as possible anyway but there are times when you might want an order a day earlier (First Class Mail tends to take a day longer than Priority Mail) in which case tell us what your needs are.
Looking for something a bit lighter than a strap, check out our Gear Wranglers. They are perfect for securing your light gear, attaching a plant to a stake or even keeping the bag of potato chips closed.
Gear Wranglers are made using 1/8″ elastic cord and a cord lock to adjust their length. The come in 12″, 24″ and 36″ lengths and are packaged 6 to a bag. Like our Rod Wranglers the elastic cord ends are secured using a zipper pull.
Order your Gear Wranglers now, if you order 3 packs (you choose the size) and put the code ROLLIE-PAYS in the comment section of our check out, Rollie will pay the shipping by US Mail. This offer ends November 30, 2016. Our shopping cart is not smart enough to pick up on this offer but be assured we will take care of it prior to your credit card being charged.
If you don’t need that many Gear Wranglers, but want a great way to keep your fishing rods corralled, check out our Rod Wranglers, you can even use them to make up the 3 packs for free shipping.
We now carry 1″ black polyester webbing with a 9/16″ reflective strip down the center. This material is thinner than the standard webbing we sell which makes it easy to sew on to bags, packs or even a coat. It is still sturdy enough to use for the adjustment straps on a backpack or with a buckle to fasten something to your bike rack.
Polyester webbing is great for many uses since it has minimal stretch and doesn’t want to adsorb water. It is also quite abrasion resistant although the reflective strip will get worn off due to abrasion. We sell this material by the foot and you can order it online or come by our shop to check it out.
The trend seems to be that all of our outerwear is getting darker and darker making it difficult for drivers to see us when we are walking or biking. Carrying a bag or pack with plenty of reflective surfaces will help you or your children stand out as our days become shorter and weather gets worse. This material is easy to sew so adding it to existing gear should not be a major issue for anyone with a sewing machine.
Here is a picture of our reflective webbing taken in a rather dark room without flash (there was a dim night-light to the left of the webbing)-
And here is a picture of the same piece of webbing taken with the flash turned on-
The webbing in these pictures was about 12″ long and the picture was taken using an iPhone from 15 feet away. It is pretty amazing stuff!
We will soon be producing quick release sail ties in a wide variety of colors. Unlike our other sail ties, these have a side release buckle, hence the “quick release”, grab loop and sewn tab so you can’t lose the male half of the buckle.
They are made using polypropylene webbing which does not adsorb water or bleed pigment. All sewing is done using A&E’s SunStop polyester thread which has advanced UV protection which helps maintain the strength of the stitching over time.
Just click the buckle closed, grab on to the loop and tab and it is easy to cinch up the sail tie. These should be available online in July, if you want some sooner give us a call at (253) 883-5800.
Are all plastic buckles the same? No they are not.
There are three main plastics that buckles and other hardware for webbing are manufactured from:
All have their strengths and weaknesses and many products are available in more than one plastic so you can choose what will work best in your application. Strength, resistance to heat or ultra-violet light and cost all factor in to what is best. So in alphabetical order lets dive in.
Excellent resistance to immersion in water
Excellent resistance to chemicals and solvents
Retains mechanical properties up to 250° F.
Poor resistance to acids
Subject to UV degradation
Good chemical resistance to oils and greases
Tough and impact resistant
Heat stabilized versions are available which meet various NFPA standards (special order with minimum quantities)
High moisture pick-up with related dimensional instability
Attacked by oxidizing agents
Attacked by strong acids
Excellent moisture resistance
Good impact strength
Degraded by UV
Attacked by chlorinated solvents and aromatics
Putting the factors together Acetal provides the best performance of the three materials (other than for very specialized high temperature applications). So why do some vendors offer polypropylene buckles and hardware? Price. Polypropylene is around 15% less expensive and if price is the driving factor, it can’t be beat. You are trading off durability but in some applications that is not needed.
When you browse our selection of buckles and hardware we tell you what each piece is made from. That applies not only to plastic but also to metal products. In the case of stainless steel, we try to identify the class of material the piece is made out of so you can tell if it is type 316 which will not even stain or type 304 where you will see some rust stains over time.
If you have any questions give us a call, (253) 883-5800 and we will try to answer your questions.
Tomorrow is the start of the 9 day Seattle Boat Show. We will be in booth number 2122 on the Concourse Level (upstairs). In our booth you will find a wide selection of side release buckle straps with polypropylene webbing, sail ties in both polypropylene and polyester webbing, jack lines, ratchet straps and belts.
If you want to special order something, we can take care of that at the show. Don’t think we just make straps for boaters, if it is made with webbing (and is NOT designed for overhead lifting or life safety) chances are we can make it. There is no minimum order so even if you just need one of something, come by and chat.
After the Seattle Boat Show, our next event is the Yakima Sportsmen’s Show in February. We will be in booth 419 from February 19th through the 21st.
How do you determine the breaking strength of polypropylene webbing? It depends. There is no industry standard way defining breaking strength. One manufacturer might test 10 samples and take the lowest strength. Another might take the average and a third might take the highest. Being a commercial grade product that is not designed for use in life safety or overhead lifting no government agency is telling the manufacturers what to do.
The industry has two basic models of polypropylene webbing, lightweight and heavyweight. American Cord and Webbing (ACW) has their 549 material that ranges from 0.040″ to 0.060″ in thickness and in a 1″ width has a minimum breaking strength of 360 pounds. ACW’s heavyweight material has a thickness range of 0.055″ to 0.075″ and a minimum breaking strength of 560 pounds.
I have seen lightweight 1″ material listed as having a 600 or even 700 pound breaking strength. Is one better or different from the other, probably not.
What makes piece of webbing strong is the amount of material (polypropylene in this case) it contains and how it is constructed. Thickness tells you something about the amount of material for a given width.
So how do you figure out what to use? First the webbing is usually not the weak point in a strap assembly. Stitching or buckles can be much weaker. A 1″ side release buckle will have a breaking strength of around 200 pounds, much lower than ACW’s 360 pound breaking strength for the webbing. If you have a critical application the only way to be sure is to make some assemblies and test them. If all you are doing is strapping up some sleeping bags, strength is not an issue.
With polypropylene webbing chafe and ultra-violet (UV) exposure are two issues which will weaken your strap. Materials like polyester offer much better abrasion and UV resistance along with a higher initial strength. If you are repeatedly loading a strap consider nylon whose ability to stretch might help dampen the load.
My article How Strong Is Your Strap covers sewing pattern choices. Searching the internet you can find other information that will be helpful but at the end of the day, build a prototype and test.
