Holdfast Stabilising Straps for Boot Carrier

Short Product Summary

The Holdfast Stabilising Straps (part 220580) give a Holdfast Boot Mounted 3-Bike Carrier — its part number is 220571 — a second anchor line, fitted by hand once the carrier and bikes are already loaded and tensioned. They're aimed at drivers who've felt the carrier rock on rough or corrugated roads.

Why This Product

The main straps on a boot carrier work by squeezing against the boot lid, tailgate and bumper rather than bolting to a fixed point, so there's always some give built into the mount. Tar roads rarely expose that give, but a corrugated gravel stretch can shake the load at close to its own natural rhythm, and each kilometre lets the wobble grow a little more, slackening the main straps bit by bit. Pulling from a different angle with a second strap breaks up that rocking motion before it can build momentum.

Key Features

• Second, opposing anchor – pulls the carrier from a different angle to cancel out its rocking motion
• No tools to fit – goes on by hand once the main load is already tensioned
• Sized for part 220571 – made to match the Holdfast Boot Mounted 3-Bike Carrier
• Heavy-duty webbing – made to stand up to repeated tensioning trip after trip

Ideal For

• Owners of the Boot Mounted 3-Bike Carrier who've felt the loaded rack rock on a corrugated or gravel stretch.
• Drivers covering long gravel routes since the rocking motion tends to build the further you drive.
• Anyone who wants an easy add-on because fitting these straps needs nothing more than your hands.

Optional Fitment / Upgrade Notes

Fit and check these straps carefully:

• Only add these once the carrier is loaded with bikes and the main straps are already pulled tight, not before.
• Snug them up just enough to remove slack without bending the carrier's frame out of shape.
• Give the whole strap setup a check after your first twenty minutes on the road, again at each fuel stop on a longer trip, and once more after any stretch of rough gravel.
• These are sized for the Boot Mounted 3-Bike Carrier (part 220571); a different strap set covers the tow ball Snap-On carrier.

FAQ

Which carrier does this fit?
This strap set (part 220580) is sized specifically to match the Holdfast Boot Mounted 3-Bike Carrier — its part number is 220571.

Why does my loaded carrier rock on gravel?
The main straps grip the boot lid, tailgate and bumper rather than a solid mounting point, so there's a bit of give built in; rough or corrugated surfaces can shake that give into a growing wobble the longer you drive.

Is fitting them a tools job?
No, they go on by hand once your bikes and the main straps are already in place.

How often should I check the tension?
Check it after your first twenty minutes of driving, at every fuel stop on a longer trip, and again after any rough gravel section.
