Product Description

4-Inch Flexible Sidewalk Sign Changeable Letters

Maximize your curbside advertising with our premium 4-Inch Portable Sidewalk Sign Letter Kit (Product Code: CFL45B). Specifically engineered for folding A-frame sidewalk signs, roadside arrow signs, and menu boards, these flexible changeable letters feature a bold block-style font that is highly visible from up to 65 feet away.

Unlike cheap, cloudy recycled plastic sheets that yellow and scratch, our letters are printed on ultra-clear, premium .030 mil thick non-reground acrylic panels. This flexible material allows you to bend the panels easily to slide or pop them directly into standard letter track without disassembly. Each panel is 4-7/8" tall, with varying widths depending on the character, allowing letters to align naturally with perfect spacing.

This massive 272-piece kit includes a comprehensive, pre-sorted dictionary of black letters, red numbers, and essential punctuation marks, giving you more of the vowels and primary consonants you need most. Designed specifically for non-enclosed open-air signs; these economy-style thin letters will warp if used inside an enclosed, locked marquee cabinet due to extreme heat build-up.

Ideal for retail sidewalk signs, HOA announcements, school events, and special promotions. Fully compatible with our Set of 5 Portable Sign Letter Tracks. Backed by our fast 1-day shipping and live phone customer support at 800-582-6366.
