The KC Xross Bar features a low profile aerodynamic design constructed from high quality 6063 T6 Extruded Aluminum in an attractive satin black powder coat finish. This makes the KC Xross Bar lighter than steel bar options on the market while being highly durable with its resistance to corrosion and rust. With pre-configured mounting holes the Xross bar can securely hold anywhere from 2 to 9 lights with ease. Slotted holes allows for extra customization and to accommodate a variety of light sizes.
