ZROADZ Roof LED Mounts are the most robust roof mount light brackets on the market. Constructed from laser cut 3/16” mild steel, ZROADZ roof brackets and kits feature a patented single thru-bolt attachment to provide a secure mount with minimal exterior penetration. Completely block out moisture and seal the roof with the provided rubber and a heavy duty solid rubber gasket for a secure and watertight installation. The patented thru-bolt fastener provides a convenient method to run wires into the cab without the worry of weather-stripping wind noise and leaks or other subpar wire routing methods. ZROADZ Front Roof LED Mounts are designed and made in USA
