Electrical Interlock System: 120vac electrical interlock with hands-free push-button operation and in-use indicator light. Interlocks allow only one door to 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 normally locked so that in a power failure, doors cannot be opened. This also allows all doors to be locked out by turning off the power switch when working beneath the chute, 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 a conduit in most applications. Check with your local building authority regarding installation requirements. Requires SKU #500282 manual switch and power supply for operation.

When ADA compliance is required, these doors can be customized with ADA compliant lever handles. Other accessories available include key locks, foot operation, and more.

A direct replacement for Midland #MB2121EI, formerly Midland Metalcraft, and replaces easily with minimal wall damage. Can be retrofitted to others chutes with sheet metal adaptors and wall modifications to fit chute door openings for doors of the same size.

Complies with building codes, NFPA-82 and ASTM standards.
