Plastic Cam Buckles from Strapworks are great for belts and light-duty straps. The buckles close with a positive lock and do not slip. They are available in a range of sizes from 1/2 inch to 2 inches, with 1-1/2 inch and 2-inch styles being the preferred size for diving belts. The plastic cam buckle is also great for making a light to medium-duty tie-down. We also carry SUPERLOC versions of cam buckles, which is a stronger, beefed-up version of our standard light-duty Plastic Cam Buckle. SUPERLOC buckles are ideal for applications that require greater sturdiness or where the buckle will be subject to specific abuse. For more information on our Plastic Cam Buckles, Please note that the 3/4 inch, 1 inch and 1 1/2-inch Plastic Cam Buckles will only work with lightweight polypropylene straps. The 2-inch buckles work with all different types of webbing, although the flat nylon is a tight fit due to its thickness. Please
