Useful for removing an obstinate oil-filter cartridge or radiator cap, a strap wrench has a loop of canvas webbing slotted through a metal handle. The loop, or strap, clamps round the filter or cap to grip it so that it can be levered off. A chain wrench has a length of bicycle chain forming the loop. It may have a grip handle or a tightening nut for use with a socket drive.
