We are proud to offer Gemini Pronto™ letters for Stewart™-brand and similar signs. These letters provide the ultimate in durability and ease-of-use. Due to their thickness, Gemini sign letters do not work with OSA-brand or sidewalk signs. Please ensure that you select the correct style of letter for your sign.

Gemini sign letters are injection molded with 0.08” thick high-impact acrylic, making them non-flexible. This heavy-duty construction prevents warping and keeps the acrylic sign letter in place under most wind conditions. Each outdoor sign letter is molded with a small raised edge that prevents the screen-printed ink from being scratched. The molded-in feet keep debris and ice from interfering with sign letter placement.


We offer several different font styles for our non-flexible sign letters. If you are attempting to match existing sign letters, please see our font comparison.

All sales for Gemini sign letters or accessories are final, and product returns are not accepted.
