PLASTIC LETTER MOUNTING METHODS

Used on all Formed and Injection molded plastic letters

Acrylic letters use the same mounts except that the letters are not hollow in back

No Mounts
NO MOUNTS

The reverse side of all formed plastic letters are hollow. No mounting attachments are produced as part of the vacuum forming process. This can be difficult to mount and produce unsightly results if done improperly. They are made this way for professional sign companies that will have their own attachment methods or choose to do it themselves by purchasing specific hardware. Also be aware that if you shoot screws through the face of the letters they will not only look unsightly but will void your manufacturer's lifetime warranty.

Not Recommended

Flange Mount
FLANGE MOUNT

(Formed Plastic Only)

The plastic has not been trimmed flush to the wall of the letter, leaving a flange through which small screws can be inserted to attach the letters to the mounting surface. This type of mount is only available for letter heights of 6" or more. Generally speaking, this mount is better suited to very large letters as the flange becomes less and less noticeable when the letter size increases.

Flange detracts from clean appearance on smaller letters

Pad Mount adjustable pads
Left (Flush Pad)
Right (Adjustable Pad)

Pad mounts are achieved with the use of perforated plastic disks or rectangles that are glued into the backs of the letters so that they are almost flush with the letter wall. Order Adjustable pads if you want a non-flush installation or for uneven surfaces. Best used in indoor situations on drywall and outside where drilling holes might be either unsightly or too difficult as in the case of very hard concrete.

The pad mount relies on silicone adhesive to glue it to the mounting surface. Long strips of masking tape should be employed to hold the letters in position while the adhesive dries.

Best for inside on drywall. No drilling

STUD MOUNT

Studs involve the use of 3/16" dia., 10-24 all threaded stainless steel or aluminum rod that screw into plastic retainer blocks that are glued into the backs of the letter.
No two letters are interchangeable, even letters of the same character. This is because the stud blocks are glued into the letters by hand and each will have unique positioning. On the pattern, a circle identifies the position of each stud where it falls inside a letter.
Drill holes for studs and use silicone adhesive to hold the studs securely in the holes.

Mounting Pattern Required
Best for outside use

Combo Mount
COMBO MOUNT

A combo mount differs from a stud mount in that the upper portion of the letter will have studs and adjustable pads that can be screwed up or down the stud.

The lower portion of the letter has nonadjustable pad type mounts. This configuration is good for uneven surfaces, such as lap siding where an adjustable top will allow the letters to be vertically plumbed.

Mounting Pattern Req.
Best for outside with uneven surface

combo all mount
COMBO ALL MOUNT

On the combo all mount, each stud has a plastic perforated disc that can be screwed up or down the stud shaft.

This allows for full adjustability over all mounting points allowing you to install against corrugated tin, curved surfaces and all manor of uneven surfaces.

The studs through pads also allows you to stand off the letters from your mounting surface, giving a greater depth or to allow for some form of back lighting.

Mounting Pattern Req.
Best for outside standoff & uneven surfaces.
