Hardware to make twenty 3/8 inch (10mm) Cat Collars, using your own webbing. Included are the following: Twenty (20) - 3/8" (10mm) contoured, side-release, Safety (Breakaway) buckles, Twenty (20)- 3/8" (10mm) Plastic Wide-Mouth Triglides, Twenty (20)- 3/8" (10mm) Steel D-Rings, Nickel plated. The buckles in these kits are SAFETY buckles, meaning they release easily when pulled on, and should not be used for applications where tension on the buckle is required. The prongs on the male half are rounded and lack the hooks which are present on normal buckles. They're great for cat collars. If the cat collar catches on something, the cat's struggling action will cause the buckle to open, freeing the cat. They should not be used with leashes. PLEASE NOTE: **Webbing NOT included.** **Instructions NOT included.** **Strap Keepers NOT included. ** This kit contains only the hardware necessary to make collars. Buyer must provide webbing and strap adjusters, if desired.
