Buying Guide: Key Considerations For Plastic Letters
- Intended use: Choose LED letters for visibility in dim venues, or flexible plastic letters for temporary signs and quick changes.
- Material and durability: PVC with UV stabilization resists fading and bending; acrylic options offer smooth, rigid surfaces for long-term use.
- Mounting method: Adhesive-backed signs are easy to install on smooth surfaces, while non-adhesive options may require frames or tracks.
- Letter size and legibility: Larger letters improve readability at distance; ensure the letter height matches your sign’s viewing distance.
- Accessibility: If accessibility matters, ADA-compliant or Braille-ready signs are essential for public spaces.
- Compatibility: For marquee signs, confirm track type (0.030″ flex tracks or Texas Tracks) to ensure proper fit.
- Maintenance: Consider easy cleaning and whether the letters are color-mitted or plain white for versatility.
