DMM's Dragon Cams offer incredible holding power, substantial expansion range, & an extendable sling to reduce the weight of your rack. The contact area of the cam lobes has a raw finish to reduce walking in marginal placements.
The dual axle mechansim provides an excellent camming range per piece, & the thumb bumper is tactile & secure. Dragon cams are available individually, & in sets for building up your trad rack.
