Louden Double-Tread Barn 



Door Track and Hanger 



Fig. 458 



The Double-Tread was the pioneer Flex- 

 ible Barn Door Hanger, and continues to be 

 one of the leading hangers in the market. 

 It is compact, durable, and serviceable, 

 simple and strong in construction and sure 

 in its operation. Thousands of these 

 hangers which have been in constant use 

 for many years are still rendering faithful, 

 efficient service — never a hitch in their 

 operation; not a cent paid out for repairs. 



Construction 



The Double-Tread is in reality two sets 

 of hangers — a set on each side of the door 

 fitted to run on opposite edges of an 

 inverted T-rail. The track is flexibly hung 

 to brackets secured to the wall, and will 

 accommodate itself to the inequalities of 

 the barn siding. The door can be closely 

 fitted without danger of sticking or binding 

 on account of the warping of door or siding. 

 This feature gives it a decided advantage 

 over all rigid hangers. The track, being a 

 T-rail, takes up the least possible room, 

 and the hanger frame is consequently 

 shortened and straightened. 



The parts of the hanger being clamped 

 solidly together on both sides of the track 

 makes it impossible for the trolleys to jump 

 the track. The door is always in place 



and ready to go. There is an absolute center draft; no side hitch to make a strain on the hanger or 



throw the door out of plumb. 



The four wheels which carry the weight of the door are fitted with turned and tempered steel roller 



bearings. Ten of these bearings revolve about a turned and tempered steel shaft.
