Saves Time, Makes My Life and Work Easier
this Thule 503 Load Stops review by Daniel
vehicle year/make/model: 2004 Chevy Avalanche pickup truck
item(s) transported: ladders, wood
These stops do an excellent job. Time to time I have to transport extension ladders or long wood materials. Everything is much easier and faster with the Load Stops. I use them with a pair of Thule 523 Load Straps.

T.T.D. asks - Does any all-purpose Load Stop brackets fit the Thule AeroBlade Bars?
ORS Crew answers - Great question. As of 2/25/2012, not in the traditional sense of Load Stops are there any that are compatible with the AeroBlade cross bars. However, we have gotten creative and done quite a bit of testing to come up with a great list of innovative, all-purpose Tie-Downs / Load Stops for the AeroBlade load bars used with all the Thule Rapid AeroBlade roof rack systems (such as 460R Podium, 450R CrossRoad, 480R Traverse etc.) You can use the following: TracRac deluxe tie-downs (sold as a pair, order 2 pairs, also need pair of rack straps), TracRac economy tie-downs kit (sold as a set of 4, also need pair of rack straps), Malone BigFoot Pro canoe brackets (sold as a set of 4, also includes pair of rack straps), Inno 451 Cradles (sold as a pair, order 2 pairs, also need pair of rack straps)
WYOCAMPER asks - We just bought a SportRack roof rack cross bars system for our Flagstaff Popup camper. Will the Thule LoadStops fit to hold a canoe on this rack?
ORS Crew answers - Yes the Thule Racks Load Stops will also fit the SportRack base rack square cross bars.
ARL asks - Will the Thule Load Stops fit on the Malone cross bars that come with the kayak trailer?
ORS Crew answers - Yes the Thule 503 Load Stops are fully compatible with the square cross bars on the Malone kayak trailers.
