What It Is

How to Use It

1. Ensure the top of the C‑section post is clean and dry.
2. Align the cap squarely over the post head.
3. Apply firm downward pressure until it clicks or fully seats.
4. Press edges as needed so it sits flush on all four sides.
5. No additional fastening required—removal for maintenance is just as simple.

Coverage Example
Use one cap per vertical post—each cap seals just one 100 mm post channel. Measure post count to determine quantity needed.
