Product Information


The new Van Mark Metal Master 20 60 Series Brake is an updated version of the older Metal Master 20 50 Series Brake. The LockMaster C Castings are all new and adds additional life to your siding brake. They are 15% lighter, and 20% stronger than the 50 series model brake C Castings. This means the brake will last longer and require less fine tune adjustments than the original model. This siding brake is made in a contractor model and a heavy-duty residential model, with the main difference being the thickness of the material each brake can bend. Easily create "W" style valley-pan bends, to soffits and roof flashing, including wide hip and ridge cap, HVAC duct & plenum work, and more. Van Mark manufactures the Metal Master 20 with a 20in. throat depth to provide more efficient, precise bends down the entire length of the brake.


  • Equipped with locking handle that has quick release feature for easy transport
  • Power Lock bar provides crisp bends without oil canning/warping
  • Cam locking system consists of aluminum and ultra high molecular weight polyethylene
  • Includes two military grade aluminum castings
  • Dual support base rails for extra foundation
  • POWERslot hinge "auto-measures" 5/8" hems
