Video Transcript for Review of Thule Replacement TracRac Ladder Rack Knob - TAKB-90030-1

Hi there. I'm Michael with Today, we're going to take a quick look at the Thule replacement knob for your TracRac ladder racks. This is going to be an exact replacement from Thule, so you don't have to worry about fit or compatibility issues. It is going to replace one damaged knob on your TracRac rack. It is going to allow you to, once again, lock your load stops in place simply by twisting the knob, so that you can keep your ladders, lumber, and other cargo in place, and prevent it from moving around on you.

This is going to fit the TracRac SR sliding racks, as well as the TracRac G2 fixed mount ladder racks, the TracRac cantilever over-the-cab extension for your TracRac G2 sliding ladder racks, your TracRac G2 Camber headache racks, and your TracRac TracOne fixed mount ladder racks, and your TracRac UtilityRac sliding ladder racks.All of those are compatible with this knob. So if you are needing a new knob to keep those load stops in place, this is going to be the piece for you. And like I said, this is a Thule product, so you're not going to have to worry about it not fitting quite right. It is going to be exactly what you need. So that's going to complete our look for today.

Again, I'm Michael with Thanks for watching.

Replacement Knob for TracRac Ladder Racks - Qty 1 - TAKB-90030-1

Average Customer Rating:  4.8 out of 5 stars   (119 Customer Reviews)

Replaces a damaged male knob on a TracRac Overhead Rack, TracRack BaseRail TieDowns, or TracRac Cargo Holder. Includes 1 replacement knob.


Fits perfectly. Also, they have improved the end stop in that it fits through the hole now. One of the two was to replace a knob where the nylon tip had gone missing after I needed to remove the rear rack. It was then that I noted that the OEM part did not allow removing the knob with the tip. No doubt how it got lost.
The replacements are a new design so that there is less chance of losing the tip.
The other knob was used to replace a broken one.


Absolutely perfect and exactly what I ordered. Unfortunately, I needed the knobs which hold the load stops on the top of the rack. I went back once I realized I ordered wrong pieces but did not see the knobs with female thread in lieu of the ones I ordered which have the threaded male lugs. I thought I may be able to remove lugs but it seems the may be molded around lugs. Could you please let me know part number or send me a link to them so I can order 4. I’m fine with everything I ordered and will keep them as there are those who like to steal these parts.

If you have the load stop for the original Track ladder rack part # 01-23321
Replacement Load Stops for Original-Style TracRac Ladder Racks or TracRac CapRac - Qty 1
then you will need knob part # TAKB-90004
Replacement Hand Knob for TracRac Ladder Rack Load Stops - Qty 1
-- Etrailer Expert Jenny N - 01/17/2022


The product is fine, however the originals only lasted approximately 2 years before having issues. The nylon stops/washers on the bottom fell off. One of the plastic handles cracked. This would be fine if they were inexpensive to replace. At this quality these should be considered disposable replaceable parts, and the cost of replacement should be much less.
I also need new ladder stops for the tracrac due to peeling surface finish and oxidation. These also are way overpriced for the tracrac version prior to Thule taking over. My rack is only 4 years old.
etrailer however did a fine job of order processing and delivering the product.


Thanks to excellent customer service, finally got the right part.


great unit, works well, trailer is great to work with!!!


seemed to have gone well installing pocket stake rubbers, bolts and used rack. cinsidering i had to cut rails from 8 ft to 6.5 and deal with fused nuts and bolts. it istalled in under an hour. no complaints besides it raining on me.
also bought the rack knobs. all are nice and work well


Works excellent, still going strong after all this time.


Couldn’t find this part in the usual place [online] ordered from etrailer. Easy and I didn’t have to set up an account!!


Quality Part just not right size for my rack


Exact replacement part. Good to have a spare or two.


Perfect replacement!
Fast shipping and
showed up faster than expected.
Definitely will shop again!


Great job thank you.

Fantastic good amount of tie downs very strong!

Thank you


Great service, pricing and fast shipping, thank you!!!


Outstanding product; I took out and put on my TracRack for 2002 Tundra and it worked perfectly. Excellent price and arrived pretty quick with just the standard delivery. Thank you.

Bought these over a year ago and they perform like I just got them a week ago. e trailer is awesome.
Coltrane1975 - 06/02/2020


I have to take away one star due to etrailer shipping the wrong item the first time and having to wait an extra week to receive the correct part. I ordered the Knobs that lock a TracRac in place on the mounting rail and was sent the Load Slide adjustment Knobs first. Both types of Knob look the same except the one I ordered have a Stud protruding from the bottom and the other ones don't. The Customer service reps were polite and corrected the mistake immediately. Good job.


Perfect replacement and delivered quickly.


Nice looking and compatible with the original knobs on my sliding TracRac. One knob out of 5 ordered had the white plastic tip missing and customer service graciously replaced the whole knob.

no problem after first year.
Walter - 05/29/2017


I was extremely happy with this product. It was the first time ordering products from and I was very pleased with the up-to-date shipping status and confirmation email of delivery. The product was exactly what I needed and it was a great quality product. I will definitely be ordering more from in the future.

  • Recommendation for Making Low Crossbars for TracRac SR System
    There is not a specific kit ready to this use, but you can add the parts needed to allow this. You will need the Nylon Inserts - part # TAFX-42008 (8) as two are required per base. Then you will need the Right Mounting Foot - part # TA01-42004 (2) and the Left Mounting Foot - part # TA01-42003 (2). Then you will need the Locking Knobs # TAKB-90030-1 (4).

  • Is TracRac Sliding Ladder Rack Compatible with Additional Lower Sliding Roof Rack
    Thule has not yet made a roof rack style connection to work with their sliding base rails but you are not the first person to ask. Basically you can make something work, but there is not a warrantied application available or a confirmed weight rating, so it would be a one-off custom. What you can do if you want to proceed is you can use the Replacement Modular Slider for TracRac G-2 Truck Bed Ladder Left Front/Right Rear # TA01-42003 and Right Front/Left Rear # TA01-42004 which are the...

    The Thule TracRac SR like # TH43002XT-501 for 6-1/2 foot bed or # TH43003XT-000 for the 8 foot bed is the correct fit for a 2018 Ford F-150. This system uses the stake pockets to mount the rails.
