The DHRUM mounting kit can be used to mount your DHRTM50200 trailer mount hose reel to a wall or a wide range of portable pressure washer frames. The clamp system securely attaches to any round pipe or square tube frame up to 2″ in size/diameter. The clamps grip to the frame to prevent slippage. The bracket consists of one powder-coat & rust-proof aluminum receiving socket, four galvanized steel clamps, and four stainless steel nuts and bolts.
