21"x18" Bottom Hinged Intake Door with Electrical Interlock and Pneumatic Operation, "M" Series

21"w x 18"h Bottom hinged, hand-operated, self-closing, positive latching, chute intake door assembly complete. Door bears a UL Label with a clear listing of 1-1/2 hour, 30 minute - 250 degree max temperature rise. Includes replaceable "T" style handle with key, latch assembly, door closer and trim. To change the "T" style handle to a pull handle with latch thumb trigger see SKU #500757. Door uses a piano hinge system for the door panel which is welded to the door and frame. The panel can not be removed or replaced. Door panel made with 20 gauge type 430 stainless steel front and 18 gauge galvannealed steel back. Closer is exposed in the door opening for ease of replacement; however, wears quicker than the "W" or "WM" series from exposure to waste. Stainless Steel trim available blank or embossed with "Rubbish", "Soiled Linen", or "Recycle".

This door is designed to work with the Midland specific pneumatic and electrical interlock system and includes recent upgrades to the pneumatic operation.

Includes a 120vac electrical interlock controled pneumatic powered door opening system with ADA compliant push button and in-use indicator light. Interlocks allow only one door open at a time to reduce clogging and enhance safety during peak usage periods. User must unlock the door by pressing the button then operating the latch or handle separately. Interlocks are designed to be normally locked so that in a power failure doors can not be opened. This also allows all doors to be locked out by turning off the power switch when working beneath the chute, greatly reducing liability and injuries.


Our 120vac Electrical interlocked chute intake doors are engineered for use on 120vac 60hz line voltage therefore the intake door electrical panels and components are UL listed. Wiring is to be in conduit in most applications. Check with your local building authority regarding installation requirements. Requires SKU #500282 manual switch and power supply for operation. 24vac replacement doors are also available.

A direct replacement for the Midland Chutes door, formerly Midland Metalcraft, and replaces easily with minimal wall damage.  Complies with building codes, NFPA-82 and ASTM standards. Made in the USA.
