Manufactured to the exact size of your opening (+0, -3.2mm), regardless of the size

• assures good seal
• for good appearance (no mismatched components: odd height header air seals, odd width nose gaskets)

Full perimeter air seals are standard on most Models

• provides as close to 100% seal efficiency as is possible with a double-acting door to control:
  • temperature
  • humidity
  • noise
  • dust
  • microbes

Factory aligned and pre-pinned hardware

• assures doors are permanently centered and, therefore, seal at nosing
• saves installation time
• assures proper installation

Choose from three (3) cast alloy cams (19mm rise, 38mm rise, Deep Seat) for operating hardware, supplied on all models (except as noted below). "Our reputation hinges on it"

• choose ease of opening / speed of closing
• wind resistance / negative pressure control

Full height shaft, style and mounts attach the V-cam hardware to the door-body and reinforce the door at the jamb (except Ultra-Lite)

• distributes the load of impact
• prevents the cracking of door facings diagonally from the hardware that is common with competitive doors

"EZ Hang" Offset Pivot Hardware supplied on Ultra-Lite (… or 19mm rise cam), Elite, and TL 250

• makes installation very simple and narrow depth fits on almost any type of jamb
• all mounting pieces are stainless steel
• very easy open / gentle close (no tension adjustment)
• stainless steel jamb guards included at no additional cost

Non-rise cantilevered offset hardware is supplied on Flap-R Door Models

All models thicker than 19mmare insulated (most: U = .16, R = 6)

• saves energy

Dozens of features from which to choose

• engineered to meet the requirements of your application for best performance
  • Durability, Energy Savings, Seal, Sanitation (DESSS)

Bumpers and impact panels available for any height and at any location

• provide abrasion resistance and puncture protection where needed

Transoms (patented), header-hung, either flexible 6.4mm thick reinforced rubber flap (recommended, and two-piece is standard), or 44mm thick horizontally mounted door panels, one-piece or two-piece – specify. (See also Dutch Doors.)

• expose less door opening area to temperature / environmental differential allows less conditioned air to escape for better control / energy savings
• lighter door panel / easier to open / less wear on door

USDA-MPI accepted* materials

• meet sanitation requirements (*for direct contact with food, vs. see "Washdown" **)
• for easy cleaning

** USDA Washdown automatic options: must specify "Washdown" with order (supplied at no charge …at least not until next price sheet):

• single-glazed (single-pane) Rectangular window or, if double-glazed windows are required, widows will be sealed to window frame
• sealed perimeter joints
• aluminum mounts (except galvanized steel on Standard XHD Model)
• 260mm raised lower bearing with internal pad recommended (at additional cost), not required, to facilitate washing floors / covebase
