Profile: TMI, LLC produces and manufactures products such as strip doors, roll up doors, insect control doors, air curtains, impact doors & traffic doors. Our energy control and safety products can be found in airports, hospitals, retail spaces, warehouses, restaurants, and any other facility. Header mount hardware, also known as "in-jamb" or "under lintel," is hardware that is mounted within the jamb of a door (within the doorframe.) Header mount hardware is used in applications where space outside of the door is limited. Header mount hardware is less common because it reduces the actual height of the door, decreasing the amount of space through which objects can pass by an inch and a half. Header mount hardware is made of galvanized steel, aluminum or stainless steel and can be ordered in both Save-T Loc™ and the standard nut and bolt design. All TMI strip door hardware comes with studs spaced every 2", thus fitting the majority of PVC strips on the market. Header mount hardware has mounting holes spaced 3" from the ends and then every 6" across the hardware length.
