Internal Flagpole Winches

Internal Flagpole Winches by Acme/Lingo

POSI-LOK internal flagpole winches were formally manufactured by A-Cos-Con, Inc of Bethel, CT.  Acme/Lingo purchased A-Cos-Con, Inc. in December of 2020 and began producing flagpole winches at their Southampton, NJ location in January 2021.

POSI-LOK internal flagpole winches are superior to other winches in the industry due to a patented design that eliminates slipping.  Other flagpole winches allow the flag to “drift” down over time.  The Acme/Lingo POSI-LOK internal flagpole winch, however, is designed with a locking mechanism that allows for years of service with NO SLIPPING or drift.  Simply insert the handle into the winch, crank the flag to the desired position and remove the handle. The winch will firmly lock in place and stay in position until the handle is reinserted and turned.   Made from #304 stainless steel, POSI-LOK flagpole winches stands up in all environments and only requires routine lubrication.  Additionally, this winch is 100% MADE IN THE USA!
