MM-350 serie - Inflatable sides and adjustable head door seals


MM-350 Model - Inflatable adjustable header door seal


The MM-350 door seal isolates the trucks from 10’-6’’ to 14’-0’’ of the ground.

It is fabricated with two verticals and an adjustable automatic head. Verticals are moulded with a series of inside spacers, allowing the air to circulate and having a plane surface on the truck end. When the door seal projection is more than 14’’, elastic cords are added to bring it toward the wall when deflating.

The headpiece is composed of two 2’’ X 8’’ dry wood lumber and an automatic retracting roll upwards or when disconnecting.

The roof consists of two galvanized steel side supports and a wooden casing, covered with 0.055 gauge translucent plastic resistant to ultraviolet rays and ignition.  Each kit includes a 1/2 hp, 120 volts, 8.6/4.3 amp motor, 1210 CFM.

All the hardware for the installation is supplied in galvanized steel.
