FIT’s LOXX® demo shows 300+ lb pull on a locked fastener under controlled conditions. That number is evidence of positive engagement under load — not a promise that one lock carries your entire highway aero load alone.
TL;DR
- 300+ lb refers to pull performance in demonstration conditions on LOXX® lock engagement
- Real covers use multiple lock points to share peel/shear
- The useful takeaway: locked LOXX® ≠ “sticky fabric hoping for the best”
- Still need correct custom cut + full install
What the test is trying to prove
Positive-lock hardware can take a serious tensile load once engaged. That is the mechanical class difference vs relying only on magnetic attraction along a perimeter.
What the test is not
- Not a claim that trailering forces equal exactly 300 lb everywhere
- Not a substitute for multi-point placement
- Not permission to install a misaligned cover
- Not a lab certification sticker for every SKU variant
How to use this as a buyer
If you are comparing covers:
- Ask how the cover stays on at speed (Mag only? Straps? Positive lock?).
- Prefer systems that can show lock engagement, not only fabric weight.
- Pair retention claims with model-specific fit.
FAQ
Where can I watch the test?
Product pages and LOXX® proof links on FIT PDPs host the hold-test video.
Does Mag have a similar number?
Mag is specified differently (pull force class of magnets / system design). LOXX® messaging focuses on locked fastener load.
Multi-point — how many?
Pattern-dependent. The system is designed so load is shared, not hung on a single decorative fastener.
Bottom line
Treat 300+ lb as proof of lock class. Buy All-LOXX® for the system — cut + core + multi-point positive retention — not for a single viral number.
