A strap wrench is used for loosening many objects with a cylindrical lid. These contain a strap or chain being pulled in tension around the object until it firmly grips. Static friction prevents objects from slipping. 

Here are the features of a Jhalani Oil filter chain wrench:

• A strap wrench is any of various types of wrenches that grip an object via a strap or chain being pulled in tension around it until it firmly grips.

• A strap wrench is handy for most household projects like knobs, pipes, and anything cylindrical.

• It can also be used to remove lids from jars.

• It is the best solution for hard-to-remove connectors.

• This gives you all the torque (twisting power) you need to twist connectors without damaging them.
