Product Description

Plastic sign letters

We name the product after the character height, not the plastic height. So a 17-1/2" letter would be printed on a 18" panel from top to bottom. The panel width varies depending on the character. A letter W will be wider than a letter I.

Jumbo red letters are designed to span across two rows of track on the portable marquee signs to create a large message. Sign letters are printed on thin flexible 30 mil plastic. The character is 17-1/2" Block style and the plastic is 18 inch.

Spell out any message with letters that slide in grooved tracking. These red sign letters sold individually.

These economy style letters will warp in an enclosed marquee due to heat. Minimum order of 10 characters.
