Features and Benefits

Fire-Rated Pass-Through Glass Window

The wire-free glass-ceramic incorporate a surface-applied, fire-rated film and is impact rated for additional safety. These windows feature a high level of clarity and offer protection from either side.

Spring-Loaded Fire-Rated Passthrough Hinge

Spring-loaded hinges provide the self-closing capability required in a fire-rated wall. Automatic closing doors also simplify operation for operators with hands full.

Insulated Fire-Rated Pass-Through Door

Terra’s fire-rated door meets UL 10B requirements for 90-minute fire exposure, including hose-stream testing. The inside of the door is lined with 2”-thick SuperWool® Plus insulation to reduce heat transfer from elevated room temperatures.

Recessed Pass-Through Paddle Latch

The recessed paddle latch withstands up to 50 lbs. of force and can be easily operated with gloved hands. The positive latch mechanism ensures that the door always latches and remains secure.

  • Passthrough Chamber Door Stop
    This stainless steel door stop limits the arc of the pass-through door's swing to 90°, preventing damage to wall, door latch and other components. Door stops can be adjusted to allow other angles.
  • Support Brackets for Pass-Through Chambers
    Stainless steel support brackets are recommended for pass-throughs deeper than 24". Brackets fasten to the wall and the body of the chamber rests upon the horizontal bar; no fasteners are used on the pass-through itself.
  • Electropolish Finish
    Electropolishing increases corrosion resistance, improves ease of cleaning, and provides a smooth and bright finish.
