C-500 Freight Elevator Entrance

(1” Frame Setback)

Exclusive to Niagara Belco, this double swing freight elevator entrance was developed in 1993 to meet the need for a protected interlock. Typical designs using surface mounting techniques leave the interlock exposed and susceptible to serious damage during loading and unloading leading to costly down time and expensive repairs. The C-500 series door assemblies feature a fully concealed interlock designed to provide years of low maintenance and trouble free service.
