Doors 



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

 is important, so is their tightness, but their quickness is vastly more so, because it 

 affords the workman Ifeas excuse for leaving them open. 



Stevenson's latest, the "Door that 

 cannot stand open." Cuts off all rush 

 of air, ends all losses from operating 

 and neglect of any cold storage door. 

 Made with port for overhead track or 

 without. The ideal freezer door. Rids 

 itself of ice. Doors lift a little as 

 they open, hence confectioners and 

 others moving liquids in wheeled 

 tanks, can have a perfectly level 

 floor. No frail spring hinge nuisance 

 to renew every little while, put off 

 each time till the entire price of this 

 door is wasted. 



All Stevenson Doors have been de- 

 veloped with these features constantly 

 in mind. The Doorframe is adjustable 

 to conform always to the Door thus 

 insuring perfect fit and freedom, with- 

 out expense or refitting. The thick 

 portion of the Door fits loosely in the 

 frame and thus avoids binding. 



The overlapping margin of the Door 

 is held tightly to its seat against the 

 face of the Doorframe by powerful 

 elastic hinges having the largest bear- 

 ings 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, hence 

 the Doorway may be 6 inches nar- 

 rower, an important economy in re- 

 frigeration. The jambs of the Door- 

 frames are straight, clean, sanitary. 

 No frail rebate strips in the Doorway. 



The opening in wall as constructed 

 in this year 1918, should be 3^ inches 

 wider and 4^ inches higher than the 

 clear size of our Doorway. Follow 

 construction numbered 1 and 2.
