SnapFit Labs: Stretch Fabric Retention System (SFRS)

Product Overview

​

The SnapFit Retention Cover System is designed to provide a clean, precise termination point for stretch fabric systems around architectural penetrations such as electrical boxes, lighting cans, sprinklers, smoke detectors, and similar elements. Each cover is custom-sized and includes integrated fabric retention grooves for secure and professional installation.

Recommended Tools

  • Rubber mallet (for compression ring models)

  • Fabric tucking tool

  • Scissors or Utility Knife

​

Check Before Installation

  • Confirm correct SKU and size.

  • Verify opening diameter matches product specification.

  • Ensure mounting surface is clean and secure. ​

Step 1 - Position the Cover

  1. Place the SnapFit SFRS unit over the opening (electrical box, can light, etc.).

  2. Ensure it is centered and flush with the mounting surface.

  3. If applicable, secure the cover using appropriate fasteners and/or glue based on substrate type.

Step 3 - Tuck Fabric into Groove

  1. Using a knife or small pair of scissors, cut an X in the middle of the SFRS unit. (Be sure to cut the X to the edge of the inner part of the SFRS unit)

  2. Using a tucking tool press the fabric into the integrated retention groove using a star pattern. Work evenly around the perimeter:

    1. Do not open grooves more than the thickness of a tucking tool + 2 pieces of fabric

    2. Avoid over-stretching

    3. Maintain consistent depth

    4. Ensure fabric seats fully into groove

Step 2 - Apply Fabric

  1. Stretch the fabric system evenly across the surface, maintaining consistent tension.

  2. Trim and finish tucking fabric into existing track system first. Ensure the fabric lies flat and wrinkle-free before moving onto the SFRS unit.

​

Step 4 - Final Trim

  1. Tuck the fabric completely into the integrated retention groove using the same stat pattern.

    1. If required, trim excess fabric carefully to maintain a clean finish.

  2. Inspect for:

    1. Even tension

    2. Clean edge alignment

    3. Secure retention
