User manual DA-LITE LACE AND GROMMET THEATER-TYPE SCREENS

[. . . ] The Lace and Grommet screen may be ordered in the fabrics listed below ­ all of which are flame retardant and mildew resistant. Trimmed with a strong 2-1/2" webbing and grommets spaced uniformly every 6 inches. Lacing cord, included at a slight extra charge, is laced through grommets and fastened to hooks on frame. . providing a completely wrinkle-free surface. [. . . ] Tie it in at all four corners to ensure centering in the frame. Then lacing should be installed around all four sides. Do not attempt to draw lacing tight until after the frame is raised to a vertical position. When necessary to install the screen to a frame already erected, and one that cannot be taken down, it is necessary to stand the rolled screen on end in front of the frame and tie it at frequent intervals to the top of the frame as it is unrolled. Before starting the actual lacing, we recommend tying the screen to all four corners of the frame to insure its being spaced properly inside the frame. Things to Remember: Practically every installation will have its own individual problem. For instance, you may find in using your old frame that it is not large enough to lace the screen on the inside, in which case you would place the hooks on the front and outer edge of the frame. For this purpose we recommend using roofing nails every six inches, leaving onefourth inch out of the wood for the lacing cord. 1 6" No. 10 SCREW HOOKS LACING CORD 6" 6" 2. 5" 6" WOOD FRAME 6" 6" 4. 5" 6" WOOD FRAME 6" 6" 4. 5" 4. 5" ZIG ZAG LACING ZIG ZAG LACING of lacing cord alternately through grommets and under hooks is a method that will produce good results. Use this method where it is necessary to lace a screen to a pipe frame without hooks. SINGLE LOOP LACING SINGLE LOOP LACING is fast since each loop is merely doubled, pushed through the grommet and down over the screw hook. Alignment between grommet and screw hook must be straight to avoid puckering of picture surface. 6" No. 10 SCREW HOOKS LACING CORD 6" 6" 4. 5" 2. 5" 6" WOOD FRAME 6" 6" 4. 5" 6" WOOD FRAME 6" 6" 4. 5" DIAGONAL LACING DIAGONAL LACING provides a desirable tension on the fabric. It facilitates putting the correct tension in the correct direction regardless of the grommet and hook relationship. DOUBLE LOOP LACING DOUBLE LOOP LACING tends to eliminate any tendency of the picture surface to creep at the edges or unnecessary puckering. This is overcome by pulling each loop over two hooks.

This is the fastest method and usually considered adequate. (Shock cord not supplied by Da-Lite. ) 2 SPRING LACING SPRING MOUNTING is a more expensive method, usually reserved for rear screens used out of doors. [. . . ] Drill 1/4" hole into ends of horizontal pieces. Use 3/8" lag bolt with washer on 2" x 4" frames at corners. Use same lag bolts and washers for 2" x 6" stock. LACING HOOKS Place #8 screw hooks 4-1/2" from inside of corners. Measurments are same for frames of 2" x 4" and 2" x 6" stock. LACING WITH ROOFING NAILS Use large head roofing nails on face of frame.
