Our latest Snap Clamp is made of clear polycarbonate plastic and is extremely durable in the sun and under harsh conditions. This new clamp has two internal ridges near the top of the curve to help with prying the clamp off of pipe. For this new design we have reduced the size of the edges and rounded the corners to limit any tearing or digging into your material. Compared to our standard 1 inch Snap Clamp these are more smooth in appearance as well as low profile for a more sleek presence. As stated these clamps are made of polycarbonate and they have much higher tolerance to the sun which helps them get less discolored over time. These work great for banners, signage and other products where you prefer the clamp to be less visible.
