Durable metal D-rings sized for 38 mm (1 1/2") straps create secure, adjustable attachment points on bags, belts, pet collars, and utility projects. The flat profile feeds webbing smoothly and resists twisting, while the black finish is rust-resistant and coordinates with matching hardware. Use two D-rings to make a sliding buckle or pair with swivel hooks and sliders. Compatible with leather, cotton webbing, or nylon strapping.
