Designs for wooden swing doors are shown in Fig. 162, and for 

 a wooden sliding door in Fig. 163. These doors are made of white pine. 

 Doors up to four feet in width should be swung on hinges ; wider doors 

 should be made to slide on an overhead track or should be counter- 

 balanced and raise vertically. Sliding doors should be at least 4 inches 

 wider and 2 inches higher than the clear opening. 



"Sandwich" doors are made by covering a wooden frame with flat 

 or corrugated steel. The wooden framework of these doors is com- 

 monly made of two or more thicknesses of J^-inch dressed and matched 

 white pine sheathing not over 4 inches wide, laid diagonally and nailed 

 with clinch nails. Care must be used in handling sandwich doors made 

 as above or they will warp out of shape. Corrugated steel with 1/4- 

 inch corrugations makes the neatest covering for sandwich doors. 



For swing doors use hinges about as follows : For doors 3' x 6' or 

 less use lO-inch strap or lo-inch T hinges; for doors 3' x 6' to 

 3' x 8' use 1 6-inch strap or 1 6-inch T hinges ; for doors 3' x 8' to 4' x 10' 

 use 24-inch strap hinges.
