Frequently Asked Questions
How do I stop straps from scratching my car's paint?
Always add a soft barrier between straps/buckles and painted surfaces — foam tubing, rubber pads, or adhesive anti-slip sheets work well. Use door-hook straps or route webbing so metal buckles never contact the paint. Keep straps tight but avoid sharp-edge contact points; use wide webbing to spread pressure.
Will soft cargo bags keep my gear dry in heavy rain?
Most soft luggage bags (including the RoofPax line) use water-repellent fabrics and double zippers for splash protection, but user reports vary. For non-negotiable dryness, double-bag valuables in waterproof dry sacks or use a sealed hard box. Expect soft bags to protect from rain and road spray but not to be a guaranteed dry-room in extreme downpours.
What's the best strap type to stop shifting on rough roads?
Use heavy-duty cam or ratchet straps for high tension combined with cross-strapping (fore/aft + side-to-side). For roof bags, the included tie-downs and Velcro restraints reduce movement; for bulky items, use two ratchets fore/aft and two cross straps. Anti-slip pads under the load further reduce movement.
Can I use these systems on a vehicle without roof rails?
Yes — RoofPax includes patented door-hook straps that fasten under the door gasket so you can secure the bag without raised rails or crossbars. When using door hooks, check door seals and test stability at low speed before a long drive; never exceed your vehicle's roof load limit.
