Review of Thule Accessories and Parts TH05738

Today we're going to be reviewing part number TH05738, this is the Thule Replacement Quick Grip Mount Assembly. This unit is going to replace a lost or damaged mount assembly. It's going to attach the cargo box to your vehicle's roof rack crossbars. Nice, easy to use design. It's going to have tie down slots located on each side. You can run a strap through there, feed it over the cargo that you're hauling in your box and use those tie down points to secure your cargo so it doesn't move around during traveling.

The claws on the foot are going to be covered so it doesn't cause any damage to your roof rack system. This part number's going to contain one assembly that's designed to be a replacement and a fit for the Thule Force Cargo Boxes all models, the Thule Assent Cargo Box all models, and the Thule Atlantis Cargo Box all models. A few measurements to take a look at real quick. Measuring from outside edge to outside edge here of the housing, that's going to be about 6 3/4". The housing is made from a nice, durable, strong plastic construction. If we take a measurement of this spread that we have here, the maximum spread in between the points on the claws coming out of the assembly, that's only about 3 1/2", internal maximum spread that's going to be about 5 1/4".

Last measurement that we're going to take is going to measure the height from the bottom of the housing to the top of the handle, that point there, that's going to give us a measurement of about 2 5/8". That's going to do it for our review of part number TH05738. .

Very interested in the part that is under this. It is the part on the bottom off the cargo carrier that holds this particular part in place. That is the piece that has broken on mine (the part being shown in this video is fine). It is held in place by a small screw, interlocked to the mount assembly in a way that allows the whole unit to slide up and down the length of the carrier.

To ensure that I refer you to the correct part(s) I will need to know the model name of your roof top cargo box. For instance, if you have the Thule Force M box, I think you could be referring to the Slide Strip # 1500056232, that is inside the box, or perhaps the Cradle # 1500056187, that goes below the box.

@LesD Nope, they are just the only parts I can find, sadly.... the specific part I need is not listed anywhere, at all, on the entire internet... there are parts that do the same thing but don't work in the same way so I cant interchange them :-( But, thanks to you I now know what to call it, the cradle. It is indeed the cradle that goes under the box, which is an Atlantis 1600, purchased in the US in around 2006, give or take a year. Unfortunately I cant post a picture here... I am wondering if it is discontinued??

@LesD Okay, I found a picture of it - the cradle on a different model. It is the part labelled "C". Cheers Gary
