The Best Glue for Attaching Letter Rails
Lets look at the best glue for letter rails. If you’re installing changeable letter rails onto a menu board, cinema sign, school noticeboard or outdoor fixture board, choosing the right adhesive is just as important as choosing the rails themselves.

Perfect for Readerboards Letter Rails
Our changeable sign rails are lightweight yet strong, making them ideal for use with high-quality adhesive tapes.
Simply apply the tape along the back of each rail, remove the backing film and press firmly into position using a straight edge or spacer template.
The result is a neat, professional-looking installation without visible screws.
Indoor Installations
For indoor menu boards, café signs, pub displays, churches, schools and retail signage, Gorilla Super Glue Tape is one of our preferred fixing methods.
It provides a secure bond while keeping the finished sign looking clean and modern.
Outdoor Installations
We’ve also had excellent results outdoors.
When fixing letter rails for outdoor signs, always make sure the surface is:
- Clean.
- Dry.
- Free from grease.
- Installed in suitable weather conditions.
For signs exposed to high winds, direct sun or heavy public use, we recommend combining adhesive tape with additional mechanical fixings for maximum long-term security.
Surface Preparation
The strongest adhesive won’t perform well on a dirty surface.
Before fitting your rails:
- Clean the surface thoroughly.
- Remove dust and grease using isopropyl alcohol where possible.
- Allow the surface to dry completely.
- Press the rails firmly into place using even pressure along the full length.
Taking a few extra minutes with preparation can make a significant difference to the strength of the bond.
Alternative Fixing Methods
Depending on your project, other fixing options include:
- Exterior-grade construction adhesive.
- Stainless steel screws.
- Rivets.
- Mechanical fixings with weather shields.
- Combination adhesive and screw fixing for large outdoor information boards.
The best choice depends on the surface, sign size and whether the installation is indoors or outdoors.

After testing numerous installation methods, Gorilla Super Glue Tape has become one of our favourite ways to fit changeable letter rails.
It’s fast, exceptionally strong, tidy to use and suitable for a wide variety of sign projects.
If you’re looking for an easy way to install readerboard rails, changeable sign channels or menu board letter tracks, this tape is well worth considering.
