What size and type of hydraulic closer does my trash door use?
Hydraulic closers for trash doors come in 8″ or 10″ size. Remove the closer from your present door and measure the length of the body of your closer (not including the piston arm). This is your closer size. Closers come in either “Regular” or “Extended” configurations. A Regular closer has a piston arm that is in the retracted position and requires force to pull out. An Extended closer has a piston arm that in its normal state has the piston arm in the fully extended position and requires force to retract.
