DOORS 



Doors are just a big valve and are a weak point in all Cold Storage. Their 

 insulation, is important, so is their tightness, hut their quickness is vastly 

 more so, because it affords the workman less excuse for leaving them open. 



The Stevenson Doors have been 

 developed - with these features 

 constantly in mind. The Door- 

 frame is adjustable to conform al- 

 ways to the Door thus insuring 

 perfect fit and freedom, without 

 expense or refitting. The thick 

 portion of the Door fits loosely in 

 the frame and thus avoids bind- 

 ing. 



The overlapping margin of the 

 Door is held tightly to its seat 

 against the face of the Door- 

 frame by powerful elastic hinges 

 having the largest bearings made 

 for Doors of such weight. Its 

 Self-Acting Roller Fastener has 

 enormous strength, is arranged 

 for padlock — no slackening as it 

 latches — the soft hemp gasket in 

 the joint is always in sight. A 

 mere touch frees and opens it 

 from either side. 



Stevenson Doors swing entirely 

 out of the passageway, when 

 opened, the Doorway may hence 

 be 6 inches narrower, an impor- 

 tant economy in refrigeration. The 

 jambs of the Doorframes are 

 straight, clean, sanitary. No frail 

 rebate strips in the Doorway. 



The opening in wall as con- 

 structed in this year 1913, should be 

 3 Vz inches wider and 4 % inches 

 higher than the clear size of our 

 Doorway. Follow construction 

 numbered 1 and 2. 



For Overhead Track Doors this 

 • rough opening should extend \ZVz 

 inches above lower edge of track 

 bar. Doorframes are secured with 

 lag screws % x4 inches, inserted 

 through front casing at A.

 threshold 1% inches thick. Con- 

 nects lower ends of Doorframe, 

 forms a part of it and is let down 

 into the floor. No feather edge, 

 no jolt, no splinters. For ware- 

 houses. Accommodates trucks. 



Fig. C. Concrete Floors. Shows lower ends of Doorframe extending down 

 into the floor 3", and connected by angle irons extending across the Doorway 

 from one side to the other below the surface.
