Great care is taken in the production of these screens to assure extreme serviceability and excellence of picture reproduction. Maximum overall size is based on fabric type.
The Lace and Grommet screen may be ordered in the fabrics listed below – all of which are lame 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. No frames are furnished, but suggestions for their construction are provided on page 3.
Lace and Grommet style screens are not recommended unless the stage has a ly loft for safe storage of the screen when it is not in use.

Suggested Methods Of Installation
Conditions in theaters vary so greatly that no set of instructions would be complete for each theater. The following suggestions, regarding the installation, when supplemented with proper care and good judgment in meeting local conditions will result in a rapid and satisfactory installation.
Installing Screen to the frame: First, and most important, is to handle the screen in a manner to prevent its being wrinkled during installation.
Safest method is to lay the frame lat on a clean loor and unroll the screen inside the frame. 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.
result in screen surface being wrinkled, torn or damaged. Da-Lite Screen Company does not assume responsibility for such damage.
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 ind 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 rooing nails every six inches, leaving one-fourth inch out of the wood for the lacing cord.

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.

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.

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.

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.

Shock Cord (Elastic) Lacing
Shock Cord Lacing calls for elastic lacing cord (approx. 3/16" dia.) and “S“ hooks (approx. 11/2") which are inserted in grommet holes. This is the fastest method and usually considered adequate. (Shock cord not supplied by Da-Lite.)
