All steel Bill Payment Depositories have quality, extra secure, construction throughout. The built in theft deterrent system makes removing articles through the depository opening virtually impossible! For additional strength and appearance, the faceplate and weather hood is all Stainless Steel. An envelope dispenser compartment with a slide-up weather resistant door is built into the faceplate. The top assembly is heavy-duty 16 gauge thick steel. An attractive bright aluminum bottom plate runs around all four sides for additional protection against road chemicals and vandalism. Custom finishes and lettering are optionally available.
