Video Transcript for Yakima CoreBar Crossbars Endcaps Replacement Review

A lot of you guys are talking about how these end caps for the Yakima core bars are falling out over time. Well, as you start to put them in and take them out, they start to crack and stuff like that. And they just end up just falling out. So, what we're doing today is just replacing them. We have a quantity of two, so you buy them by the pair. So if you need to replace all four, go for that.

But if you just need to replace two of them, you can just grab one of them. So, it's literally the same exact thing that came with your core bars. They're going to fit the exact same but it's just gonna be a little bit more of a tight fit. So if you lost them, we got the replacement part for you, just so we can protect that inside. Since these are made of steel, making sure that this cap is on there is going to be ideal.

Because we don't want any of that to rust out. If water gets in there, it will eventually rust out. The outside is protected by some powder coat, but the inside is not. So, all you gotta do is just grab these end caps and they will fit on any length bar that you have. Just make sure you have the core bars.

If you don't know which ones you have, just make sure that you don't have a T slot on top. And if that's the case, then you got a core bar and these caps would fit. And that's basically it. There really isn't a whole lot to this part. It's just a replacement part to what you already have.

So if you need it, etrailer's got it..

Looking for end caps for my Yakima roof rake, a friend mentioned trailer. Sure enough, they had them in stock and shipped them right away. WOW!!! That’s terrific customer service. Never mind that no one else had them in stock. Got my order delivered to Rhode Island in less than a week. The experience was so good, I’ve ordered another set. I will certainly be back for additional products. Very impressive.


The Yakima End Caps were delivered on-time and for a great price.


The caps were perfect. They came quickly. Price and shipping costs were the best of any other supplier. I would definitely order from etrailer again. Thank you.


Product exactly as described and arrived early. I would purchase from again.


This works great. You can't beat the quality of OEM parts. Fits exactly as the original.


Exactly what I needed. Quick shipping and great online ease while checking out.


The customer service was outstanding. Letting me know every step of the way. My items were back ordered for 8 months. They still updated me periodically on the eta of the items. Great job etrailer.


These had been out of stock for a long time and then they just showed up. I was very happy to see them. It was not e-trailer’s fault that the manufacturer did not have them. Have used e-trailer many times and always been very happy.


I needed these rack replacement parts and buying these was super easy and reasonably priced. Shipping yo am APO was a mega benefit too!!


These replacement end caps arrived on time and undamaged and fit perfectly. Thanks etrailer!


perfect replacement!


As easy a process as there is! Well done etrailer!


Great Price...Great Coustomer Service...Fast Delivery!


Very fast and only place i could find my parts!


Fit perfect. Cost was right, quick shop ping


Took a long time to get here, but they did come and fit the Core bars just right


Customer service was great! Item received as described. The personal attention was much appreciated from the customer service agent!!!


hard to find this exact part I needed


Exact replacements for the lost caps. Will be sure to put some sort of adhesive on the inner part of the cap to keep these caps from falling off again.


Perfect fit! Quick delivery and a great price. Thank you!


These Yakima end caps were hard to find, and I was glad to find a source other than that big box online site. These end caps fit TIGHTLY on the Yakima core bars, which means they will admit less water and be less likely to be knocked off by accident. I recommend these end caps.

After one year, the end caps are still in good shape. No problems.

Exactly what I needed faster than I expected !!!


Product arrived quickly and was exactly as described.


I was glad to see you had this Yakima product in stock and at a reasonable price. The USPS delayed this delivery,which was disappointing, but not your fault. This was my second order from etrailer and I am impressed with the products and customer service. You just may have a customer for life.


Arrived quick and exactly what was list ed
