ALU-MAX buckles
Our ALU-MAX side-release buckles are made from aluminium with a stainless steel pin and spring, rated to 226 kg (500 lbs) breaking strength and suitable for use in sub-zero temperatures. The design is patented across the US, EU, Canada, South Africa and Australia, and is our strongest side-release option, a popular pick for dog collar builds and heavy-duty gear.
ZINC-MAX buckles
ZINC-MAX buckles offer the same side-release mechanism in a zinc alloy body, a solid, cost-effective alternative to ALU-MAX where extreme cold resistance isn't a requirement.
Metal safe lock and Conway buckles
For projects where accidental opening isn't an option, our metal safe lock buckles add a secondary locking mechanism to the standard side-release action, pairing well with a snap hook for a fully secure collar or lead build. Conway buckles offer a simpler, adjustable single-bar design, a lightweight metal option for lower-load straps and accessories.
Sizes and materials
Available in aluminium, brass, stainless steel, steel and zinc, with feed-through sizes from 10 mm up to 50 mm. Match the feed-through size to the width of your webbing or BioThane strap for a clean fit. Looking for something for a belt instead? See our belt buckles range, including roller and double bar styles.
Complete your build
Pair your metal buckle with a ring, a tri-glide for adjustability, or a concho for a decorative finish. Buying in bulk? Check our accessory package deals for discounted sets.
