The Louden Adjustable Hanger for Bird-Proof Barn Door Hanger is 

 without doubt superior to other hangers where conditions make an ad- 

 justable hanger necessary. One man with a monkey wrench can quickly 

 and easily adjust the hangers so that the door will clear frost-swollen 

 ground that would make the door rub at the bottom, or make the door hang true where the siding or 

 joists have become warped out of shape. The Louden Adjustable Hanger makes it possible for one man 

 to hang the heaviest door, as the trolleys are run into the track before being attached to the door. 



Fig. 1052 shows front view of Adjustable Hanger. By turning the eccentric (E) with a wrench, the 

 door may be raised or lowered as desired. The bolts (C and D, Figures 1052 and 1053) when nuts are 

 loosened allow the door to be adjusted up and down, while the bolt (B) (Fig. 1053) permits the door to hang 

 closer or farther from the barn as desired. 



Fig, 1053A shows how the door is "hooked" into the trolley-strap. This is the feature that makes 

 hanging a door an easy task. 



Double Bracket for Bird Proof Track Fig. 1204 



It is often necessary to hang doors 

 in such a way that one can slide past 

 the other. For such an arrangement 

 we furnish a double track support 

 from which two sections of Bird Proof 

 Track may be hung, one just outside 

 the other.

 Double Supporting Bracket 



Fig. 1204 



This equipment is the same in every way as the regular Bird Proof, 

 except that the supporting bracket is longer, and has supports for 

 two track brackets. 



The doors hang true and fit snugly. There is no waste space 

 between them.
