Smooth aluminum rail caps are the benchmark for durability when it comes to aluminum rail caps. The satin mill finish is coating free to ensure there will never be any chipping, flaking or rust. All Westcan Manufacturing’s rail caps are a no-drill installation and come with non-corrosive and stainless steel hardware. The rail is built from structural grade 1-1/2″ aluminum tubing and is complete with a clear anodized finish which will help your rail caps look great for many years to come. All rail caps are to be use with your choice of any Westcan cab guard and installation kit.
