Installation Checklist

  • Check Window Frame Depth

    Ensure your window frame has at least 1.5" depth for proper tension rod fit. Measure from the front edge of the frame to the window glass to confirm compatibility with no-drill mounting systems.

  • Consider Adhesive Tracks

    Removable adhesive mounts work perfectly for shallow or non-standard windows. These damage-free solutions provide secure hold while protecting your walls and frames from drilling damage.

  • Choose Lightweight Fabrics

    Linen, cotton blends, and sheer materials work best with no-drill systems. Lightweight fabrics ensure your tension rods and adhesive mounts can support the weight without sagging.

  • Test Before Committing

    Order free fabric samples to ensure the color and texture match your space. Testing samples in your actual lighting conditions helps you make confident decisions before purchasing full-size treatments.
