ADFORS Flat Screen Spline (100 ft)
The right spline for most Florida cages — Flat vinyl spline — the shape most modern Florida pool cages use (not the round spline windows take). The #1 thing DIYers get wrong: pull your old spline to confirm shape and size before buying.

Pros
- Flat spline is what most modern Florida pool-cage frames specify — the correct shape where round spline won't seat
- Owners find flat spline noticeably easier to work with than round
- 100-ft roll covers a multi-panel cage
Cons
- Wrong-shape or wrong-size spline is the #1 DIY mistake — you MUST pull your old spline and match shape (flat vs round) and size before buying
- Older cages and windows use ROUND spline (.140–.175) instead — check yours; a round multi-pack is the hedge if you're unsure
- Measure the groove with calipers, not a tape measure
