A cap or tonneau cover only works if it is fitted properly. Clamp placement, rail alignment and sealing all decide whether the box stays dry and whether the paint under the rails survives the winter.
We measure your box, confirm the right model for your year, make and bed length, then install it in-house, including wiring for third brake lights, interior lighting and remote-release hardware where the model calls for it.
We also re-fit and repair covers and caps that were installed elsewhere, replace worn seals and struts, and swap hardware between trucks when you change vehicles.
