- TH503

Works fine, but doesn't slide very easily along the bars. 163575


Hi Paul, these do fit tightly to the bars. This is to ensure that no matter the size of the load, these will not move and that they will remain secure.

Ask the Experts about this Thule Accessories and Parts

Do you have a question about this Accessories and Part?

  • Will Thule TH503 Load Stops Fit 1" x 1" Square Crossbars
  • The Thule Load Stops # TH503 were designed to fit the Thule square load bars which measure 1-1/4" wide x 7/8" tall. If the 7/8" height isn't something that will work for your application then the next closest things we have are the Loads Stops # A70770 which are for the 1-1/4" x 1-1/4" square Adarac ladder rack crossbars.

  • Thule Load Stop Replacement Stop
  • I have a solution for you, but unfortunately Thule does not offer the load stops as single items, and to replace the Thule load stops, you'll need to purchase part # TH503 which is a four pack. If you're OK with mismatched pairs, Rhino Rack's Load Stops, part # RRRLH2 are similar stops available in a 2 pack that uses a clamp instead of the tightening knob to clamp into the channel of your load bars. Its a tight fit, but they are compatible with Thule AeroBlade and Yakima JetStream bars.

  • 2015 Subaru Forester Limited Roof Rack Recommendation for Carrying Ladders
  • For your 2015 Subaru Forester that has raised rails that run from front to back the Thule Roof Rack part # TH45050 has been confirmed as a fit and would work well for your vehicle. For load stops for the ladders the part # TH503 would be recommended and then for straps # 34413 for ratchet straps. If your ladders will be 20 feet long on the roof of your vehicle you will need to check your local DOT for regulations on carrying an item that long.

  • Roof Rack for a 2003 Toyota Tacoma to Carry Canoe and Ladder
  • The Sportrack Semi-Custom Roof Rack part # SR1005 is a semi custom fit roof rack that offers a great price but it does not fit quite as well as some of the other roof rack systems. Unless you absolutely have to have the most inexpensive option I would not recommend this rack for you. A much better option for you since you plan on carrying longer items, (canoe and ladder) would be a Thule Roof Rack with Goalpost Hitch Mounted Load bar that consists of the following parts: Single Square...

  • Roof Rack and Tie Downs to Carry Lumber on a 2014 Nissan Juke
  • What I recommend is to add some load stops to the roof rack crossbars so that you can support the load side to side and use straps to secure the lumber front to back and tie off to the load stops. First you will need a roof rack for your 2014 Nissan Juke. The most cost effective roof rack that is a true custom fit is from Inno using square bars # INB117, feet # INSUT, and fit kit # INK399. Then for load stops I recommend # TH503 because they are designed to fit Tule square bars which...

  • Thule Ladder Rack for Thule Roof Rack on Leer Camper
  • Typically people use load stops as a way to secure ladders on roof racks. For a load stop that fits Thule square bars we have the # TH503. Then for straps we have the ratchet straps such as # 34413 which can be used to secure the ladders to the bars.

  • Best Way to Carry Ladders on a 2003 Chevrolet Suburban
  • For your 2003 Chevrolet Suburban Z71, I recommend using the Thule Square Load Bars System which is composed of the crossbars part # TH712400 and the mounting feet part # TH710401. This system contains square load bars that are 58" long and have a 165 lbs capacity. However, you will want to rummage through your owner's manual to see if the vehicle's roof capacity is lower. If it is lower than the above crossbars then this is the rating you will need to abide by. In order to secure the ladders...

  • Can Erickson Ratcheted Tie-Down Ropes be Used to Secure Lumber on Roof of a 2006 Chevy Malibu Maxx
  • I would not recommend a rope tie down such as # 01801 for transporting lumber on the roof of your 2006 Chevy Malibu Maxx. Using ratchet straps such as # EM04418 provides more surface area contact with the wood and you can get them tighter than # 01801. If you were to use # 01801 or something similar I would recommend putting eye bolts in the ends of each piece of wood on each side, running the rope through those, and securing the rope at the front and rear of the vehicle. Then you could...

  • Will the Thule # TH503 Load Stop fit on my Thule # TH440 Specialty Railing Mount Roof Crossbars
  • Yes, the Thule Specialty Railing Rack with Load Bars # TH440 that you have uses Thule standard square bars and the Thule Load Stops # TH503 that you referenced is designed to fit the standard Thule square bar so it would work.

  • Will Thule Load Stops Fit Rhino Rack Euro Square Bars
  • Technically yes the Thule Load Stops # TH503 will fit around the Rhino-Rack Euro Bar Crossbars, like part # RREB126B, but please note that the Euro bars are slightly smaller than the Thule SquareBars (1-1/4" wide x 7/8" tall), like part # TH712500, so there is some play once they are installed. The next best option would be to replace your Euro bars with Thule SquareBars so that the load stops fit properly. If you let me know the year/make/model of your vehicle I can let you know what...
