Walk-In Cooler Door Add-ons

Walk-in Cooler additional options and accessories are frequently requested.  Add-on accessories range from simple items to sophisticated, including state-of-the-art temperature and humidity recording devices. If you have a special need, please contact us, we’ll be glad to help.

Deadbolt Handle Latch  Deadbolt Handle Walk-In Coolers

When added security is necessary a deadbolt handle latch can be installed. The deadbolt handle latch can be activated by a finger slide from the outside and locked by key in an open or closed position. A twist-off knob disassembly is installed on the inside which eliminates the possibility of being locked inside the walk-in.

Vision Ports  Walk-In Cooler Vision Port

Vision ports give you the ability to see inside the cooler or freezer without opening the door. Vision ports come in two sizes, 14” x 14” and 14” x 24”. Low temperature walk-ins require the vision port to have a heater around the perimeter. A heater is not necessary in a cooler unless it is located in a high humidity area.

Padlocking Hasp with Inside Release  Padlocking Hasp for Walk-In Cooler

When added security is necessary, the locking hasp is an excellent way to achieve that security. The locking hasp conforms to OSHA codes that require a safe and easy inside safety release.

Door Gasketswalk-in cooler Door Gasket

The door gasket is a vinyl material with a heavy-duty magnet that adheres to the metal on a door frame. The gasket design allows for quick and easy replacement in the event the gasket should ever need to be replaced.

Bottom Sweeps  walk-in cooler bottom sweep

In most models the bottom sweep is a double wiper gasket that is installed on the bottom edge of the door. This allows the gasket to just barely sweep the building floor. Upon installation, the gasket is easily adjusted using a screw driver. In models with a Simpson Cooler floor, and flush door or interior/exterior ramp the gasket is installed to sweep against the threshold.
