Hillman Fasteners 839520 Reflective Adhesive Letter U 3 in

Product Description

The HILLMAN FASTENERS 839520 is a 3-inch die-cut adhesive letter U printed in black on a reflective silver mylar background. Designed for high-visibility labeling and signage applications, this thin-cut style letter provides a clean, low-profile appearance on flat surfaces. The self-adhesive backing allows for tool-free installation on most smooth surfaces. Fade-resistant construction makes the letter suitable for both indoor and outdoor use. Each package contains 6 individual letters, making it practical for multi-unit or bulk labeling jobs. At 0.3 pounds per package, the 839520 is a lightweight, easy-to-handle component for facility maintenance, property management, and signage crews.

This adhesive letter is used in residential and light commercial settings where permanent or semi-permanent identification is needed. Common applications include address marking, equipment labeling, door and suite numbering, and facility signage. The reflective silver mylar background increases visibility in low-light conditions, which makes it a practical choice for exterior address displays and emergency access identification. Property managers, facility maintenance technicians, and sign installers are the typical end users.

Installation Notes

Clean and dry the target surface thoroughly before applying the adhesive letter, as dust, moisture, or grease will reduce bond strength. Peel the backing and press firmly from the center outward to eliminate air bubbles. For exterior address applications, verify local code or municipal addressing requirements for letter size and placement before installing. No special tools are required.
