Short on Space? No problem we created our patented heavy-duty weight bearing wings to provide all the extra working space you need. Each wing holds up to 40 lbs and gives you additional working space of 20" x 15" per side. Designed to mount easily on the top of your rig when you need them and fold away snuggly into any of our slant rack systems ( 6u and up) when you don't, all RRMW wings come in a 1U metal rack mount storage tray for convenient transport. Your workplace problems solved! Another patented Road Ready Design!
