TODCO patented the Transportation Core™ a 3/4" 7-ply premium-grade plywood that forms the foundation of the door.
It has a hardwood outer veneer that virtually eliminates wood grain "telegraphing" giving a smoother more uniform look that lasts.
The TOUGHSHELL® system is a multi-layered formulation of liquid polymers that are specifically designed to work together on wood substrates and provide a state-of-the-art defense against moisture abrasion temperature extremes harsh chemicals even UV damage
Standard on all TODCO Dryfreight and TODCOLD® doors only EverWare™ rivets give you the protection of stainless steel – without the cost.
May be used in two different ways: as an OPEN only control (all LiftMaster operators) or as an OPEN/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring).
In the latter case pulling the cord will open a fully closed door close a fully opened door and reverse a closing door.
Pulling the cord whlie the door is opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).
