Features and Benefits

Critical Dimensions

Fire-Rated Pass-Through Chambers Without Windows

Chambers Tailored to Your Requirements

Modifications are no problem, as long as you keep these points in mind to retain the UL-B fire-rating:

  • Door thickness cannot be modified
  • Window dimensions cannot be modified
  • Pass-through chamber width and height dimensions other than what is shown in the ordering chart are possible, but are restricted to the outside dimensional (OD) range between 24"W x 18"H and 36"W x 48"H

Discuss your specific needs with a Terra Product Specialist.

Fire-Rated Pass-Through Installation

Fire-rated doors are designed to be mounted flush with the wall, with the body of the pass-through extending into the unclassified room (see illustration).

Access Clearances
  • Width = (Nominal Chamber Width) – 1.88"
  • Depth = (Nominal Chamber Depth) – 0.12"
  • Height = (Nominal Chamber Height) – 1.25"
  • Wall Cut-Out = Add 0.5" to chamber width and add 0.5" to chamber height
Pass-Through Support Brackets

Terra offers support brackets and hardware to ensure secure mounting (order separately). In most cases, a bracket kit provides ample support. Select support brackets for 36"D (914 mm) wall-mount models to brace the larger chamber. Two brackets are recommended for wide chambers (installed side-by-side on the wall).

Continuous-Seam Welds Eliminate Particle Traps!

CleanSeam™ Pass-Throughs feature fully welded, seamless interiors, to eliminate hard-to-clean cracks and crevices that can harbor contaminants. The continuous-seam welds are ground smooth to simplify cleaning and sterilization.

Pass-Through Chamber Interlock

Terra’s automatic mechanical interlock prevents cross-contamination by allowing one door to be open at a time. Encased in stainless steel, the mechanism is rated for millions of operations, more than enough to last the lifetime of the pass-through.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

Stainless Steel Reinforced Doors and Handles

Doors on professional-grade pass-through chambers are reinforced with stainless steel frames, which lend rigidity, improve the seal, and extend the service life of the doors.

One Piece Elastomer Gasket

The white, “e”-shaped gasket provides a flexible seal that will not creep or deform over time. The gasket is made of a non-outgassing, thermoplastic elastomer that is resistant to harsh chemicals and extreme temperatures.

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.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

  • 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 and improves ease of cleaning with a smooth, reflective, mirror-like finish.
