Single-Door Ordering Instructions:
1. Find the desired lock-prep type (cylindrical or mortise)
2. Choose the door size
3. Specify lock location (RH: right-hand, or LH: left-hand) to a Terra Product Specialist at time of order. For reference, when looking at the “clean” side (no connecting hardware visible around window frame), determine location of locking mechanism.

fire rated door
 
fire rated door
  • Designed for fire-rated facilities; get as much as three hours of fire-protection
  • Single- or double-door models
  • Wired-glass windows  (single-door only) are fire-rated and impact-rated
  • Windows allow visibility into the connecting room
  • Door/frame made with rugged 16-gauge white powder-coated steel
  • Single-door lock prep configured for either cylindrical- or mortise-style locks; double-doors have cylindrical lock-prep
  • Doors thermally insulated with honeycomb padding, giving them added structural strength

Safety and security are part of your facility’s standard operating procedures, so get the best option for cleanroom entryways. Doors and frames are 16-gauge, white powder-coated steel, making them strong and cleanroom compatible. These steel, fire-rated doors come complete with frame and lock prep; hinges, closer and lock mechanism not included.

Windows (single doors only) provide visibility into the room beyond, and maintain the high ratings outlined by UL and ANSI for fire- and impact-rated safety windows. Wired glass is ¼"-thick with a surface-applied fire-rated laminate. Windows are held in place using non-contaminating silicone caulk.

Two lock-prep options are available for single-door models. The cylindrical lock prep is government 161 with 2-3/4" backset; the 86 mortise lock prep has a 2-3/4" backset trim cutout. Locking mechanisms preserve the safe fire-rating of the door. Preps can be placed on left- or right-hand sides (specify at time of order).

Double doors come with cylindrical-lock preps for installation of desired handles. The 1.75"-thick doors are left-hand reverse (LHR), with the doors opening out from the room. Sixteen-gauge, UL-listed, powder-coated steel frame is included. Total door-opening dimensions: 71"W x 80"H (1829 mm x 2032 mm).
