YKK® Side Release Extreme Temperature Buckle Black is a strong buckle for applications that require durability and environmental resistance. This buckle is made from high-grade polyacetal (POM), a strong plastic that bridges the gap between metals and ordinary plastics in stiffness, hardness, stability and toughness.

These buckles are resistant to water absorption in highly humid environments. They also stand tough against extreme hot and cold temperatures. The side-release structure prevents accidental opening but can be easily released with one hand. This buckle's impact-absorbing design makes it great for use on backpacks, camping gear and other items that will be used outdoors.

Working Temperature Range: -40℉ to 347℉ (melting point)
