1" Black Locking Side Release Buckle

1 inch black locking side release buckle

Locking side release buckle for 1" webbing is designed to be attached to flat surfaces and is often used to hold down spa (hot tub) covers. Each buckle comes with a key.

This is not an adjustable buckle. You will need to use a single bar slide or single lock (ladder lock) buckle if you want to make an adjustable strap.

In many areas there is a requirement that spa covers be locked to keep small children from getting injured. The most common specification cited is ASTM ES13-89 which has been replaced by ASTM F1346-91 (2010 version). This buckle is sold to spa cover manufacturers that need to comply with these regulations. ASTM was founded in 1898, well before spas were invented, and was originally called the American Society of the International Association for Testing and Materials- just in case you are looking for a bit of history.
