The J hangers are extremely popular when setting up a workshop extraction system, as they keep the hose out of the way, whilst at the same time being accessible, allowing you to rearrange hoses without removing clamps or brackets. The brackets are made from a thermoplastic polymer, which is impact resistant and has structural strength and stiffness. They can be face or side mounted to walls to securely hold 102mm industry standard dust hose or dust pipe in position and are especially handy if you wish move lengths of hose to access machinery. They measure 370mm in length and are supplied in a pack of 2. ©
