JaCor offers a complete line of installation services including bottom rolling hangar doors. This 105' wide x 22' high, 6-leaf, bi-parting door system was installed for Signature Flight Support in Milwaukee, WI. This bottom rolling door system was retrofitted onto an existing aircraft hangar. Refurbishment to the hangar included demoing the existing endwall and adding a new PEMB endwall, new concrete, and a new bottom track system, along with the new hangar door and upper track system. Many hangars are in need of a new door system, but the existing hangar is still in good shape.
