Video Transcript for Review of BAK Industries - Tonneau Covers - PARTS-356A0011

Today, we're going to take a quick look at the replacement drain valves for BAKFlip truck bed tonneau covers. Now, this comes as a quantity of two, so you'll have one for either side. And it's going to fit a variety of BAKFlip tonneau covers, including the BAKFlip F-1, the G-2, HD, Fiber Max, the VP, and Dura CS and CSF-1. This is just going to slide onto the end of your side rails, and provides that drainage tube out so that you don't have to worry about any water sitting in those side rails and causing any damage or corrosion.Now, you'd be using these with the drain tubes themselves, which are sold separately. And that's basically just going to be a little hose that you push onto the end of the valves, and that helps to channel the water away, put it outside of your truck bed, and just acts as a little conduit for all that rain, water, and moisture to go.As far as dimensions, it's going to be .. Each valve is about three inches long by about an inch, maybe an inch and a 16th wide, and overall height or depth, however you want to look at, it is about 1 3/8 of an inch.

Can move it over so you can actually see that.So again, it is a direct replacement from BAKFlip, so it should fit all those tonneau covers that I mentioned before. It's just an easy install, slides onto the end, and then you can hook up your drain tubes.That's going to do it for our look at the replacement drain valves for the BAKFlip truck bed tonneau covers.

Replaces the drain valves for your BAKFlip truck bed tonneau cover.


I was really happy to find this part. But the cover it self is still leaking. I’ve tried everything and can’t tell where the water is coming in at. Everything I put in the bed of the truck gets wet and is ruined. Because of the cover leaking. This cover is supposed to be top of line. How can you help me?

You mentioned that you have not been able to determine where the cover is leaking. I recommend completing a water test with the cover. For a water test you would need to spray water up into the air, and let it fall onto the cover in the same way rain would. You may need to put your thumb over the hole of the hose to pressurize the water, to help simulate rain s. Try to avoid aiming the spray directly at the cover near the seals and corners because it will force the water through. It would be beneficial to have someone to be under the cover to get a video recording of where the water comes through.

Holding up great. Had to replace the ones that came with my bed cover but these are still going strong a year later.


A direct replacement for a damaged EOM part. Fits perfectly


They fit perfect on my 2017 F150


Genuine five star rating. I bought this set a year ago and it was exactly what I needed. Not much to it but a cheap piece of plastic that broke off of my toneau cover. These guys were about the only place I found that had them and for only $8. I just got a follow up email from them this morning to check on my satisfaction. After a year! For an $8 piece of plastic. That’s true customer care right there boys and girls.


Just like the original parts! SUPER FAST SHIPPING! Local Ford dealer told me it would be about a month before they would arrive, had them to me in 2 days. If they freeze and break again in the cold NY winter, I will defiantly buy them again from


I was glad to be able to find these as I was told that I would not be able to find replacements. Exactly as advertised.


Received part in the main, good timing say I didn't pay extra on shipping. Just installed part on truck bed cover right after work on a Friday. Yea hope your guys keep on sending good products. Thanks again.


Works perfect! I got my bed liner sprayed and company lost a drain cap. Luckily Etrailer has replacements and for reasonable price.


This was my first purchase from etrailer. I was very impressed with the quick response with the purchase, the note that it had been delivered. There was a delay to to the pandemic but when I ask for an answer for the delay I was presently surprised with the quick follow up. The folks now how to run a business and their professionalism will make me a life long customer. Thank u ETRAILER!!!!


Product fit my 2012 Ford F-150 Ford custom accessory cover and replaced my broken ones. Product arrived before expected delivery date. Great company to deal with!


Work perfect


Just as described.. blazing fast shipping.. I've purchased here numerous times and will continue to do so. Always a great experience @ etrailer ??


Easy to find what I needed!!! It got here in 2 business days! Would definitely do business again!!!


We were very impressed with how fast we received our shipment..ordered Oct 26 and received Nov 4 (Missouri to Calgary AB). The drain valves were the exact part we needed.


The product worked well, replacing my lost drain connectors. Thank you


Part is not durable to with stand the heat and becomes brittle and continues to break


Part fit my tonneau cover perfectly, shipping time was reasonable considering it was coming from US to Canada.

Bunches !
