Speaker 1: Today we're taking a look at the replacement cover for Strongberg Carlson electric trailer jack.

It also comes with a new seal, which creates a weather tight connection so that's going to do a great job at keeping dirt, grime and moisture out of the manual override area.That's going to do it for today's look at the replacement cover for Strongberg Carlson electric trailer jack.

REPLACEMENT CAP FOR THE ELECTRIC JACK
The leveling part did not work. When it was level it said it wasn't... but it looked nice and covered the hole. We traded the trailer in that we bought the part for, so no longer have it.
Product came quickly and perfectly replaces the cap/level that cracked in the cold weather of Michigan.
fast shipping (to Alaska too) and exactly what I needed. the replacement part is also of slightly better quality than the original part that came with the jack assembly - at least it feels heavier and sturdier.
Everything is fine.
Only really needed the center level piece, but this fits perfectly on the Jack.
It's perfect. We had to replace our electric lift. Gander RV put the lift on but manual override cover level had no water in it so the leveling bubble didn't work. Shipping was sooo quick, it was unbelievable. Its perfect, Thank you.
This item was a perfect fit for my replacement needs. The only reason why I did not give it 5 stars was because of the price. I feel that the price for a replacement cap such as this one should be around $15 or so. It cost double that which I believe is ridiculous. I don't understand why RV / Trailer parts are so expensive even for a simply item such as a replacement cap. I hope that the RV/Trailer industry make parts more reasonable priced, I don't it though.
Worked as a replacement for Replacement Manual Override Cap for etrailer A-Frame Electric Jack - Black!
Easy to find on a great website and fast delivery on a small part for my travel trailer. And at a competitive price. We love the bubble level on a trailer tongue jack. Good job etrailer!
I am happy I found Your website for etrailer.com this replacement part works perfect, This manual override cover fits snug and locks into place on our 2019 Sporttrek travel trailer jack. We will definately keep your website for future use if we need anything.
I placed an order with e-trailer after a little research on 2 items I needed. First item a bubble/level cap that sits on top of my trailer electric jack stand. Sealing out the elements. Looks like the original OEM part. Second item did not come with the trailer but I wanted to put a weather boot over the jack stand head. Kudo's to representative Anna E,who was quite pleasant to speak with understood exactly what I was talking about, product knowledgeable. Thank You Again Anna.
Perfect fit, nice and tight

Its great
Great service . And delivery was fast.
I had replaced the hand operated tongue jack on my travel trailer, with an electric jack, well my cover had came off, and the south Texas heat took it's toll on the plastic override / level cover.
The replacement works as it should.
This is a great product for any trailer if you want to know if the trailer is level without having to pull out the old standard level. Before I always had to ask(shout at) my spouse if it is level yet. Now I can see it easily from the jack power button.
My jack is not a Stromberg Carlson model but it still fit the opening on the jack top. It was a little loose fit but with a piece of plastic bag I was able to make it a secure fit.
This part was missing from our trailer jack when we bought the trailer leaving a hole in the top of the jack cover. Glad to get the missing part ! Part fit as it should, looks good ! Thanks !

Still working just fine.
When the original leveling bubble that came with my RV got cracked and lost the fluid, I needed a replacement. This attaches to the electric tongue jack,to aid with leveling and also serves as a cover where the manual hand crank attaches if needed. This is an exact replacement and works perfectly.

After a year is still works great and I am happy that I was able to locate this replacement
Maybe I'm missing something but I don't see how this part is supposed to fit in it's intended place. I thought I'd be able to angle it in to get the flanges to pop in but it won't go. Unless there is an alternate part, I'll need to cut the hole to match the part so I can drop it in and twist to lock. (See photos)

Sorry about that, Anthony. This cap is specific to the Stromberg Carlson Electric Trailer Jack # JET-3755, as stated in the description. I don't think there is a way to get it to fit a Husky Suspension Pro 3500 without modifying either the jack or the cap to get it to fit. If you are not willing to do that, I can definitely get a return started for you. Just let me know if you wish to proceed this way.
The fitment is good and the product fastens tightly, but the gasket does not stay in the cap. The gasket has to be held into place every time the cap is installed. If the gasket falls out of place when installing the cap, the cap will not fasten tightly, the cap may fall off while driving and water will certainly make it's way into the housing.
Perfect fit
A bit pricey but was what I needed.
Exactly what I needed for my trailer jack. Fast delivery of item. Thank you.
Nice product, quick to ship. Good commu nication
The last freeze this past winter cracked the original cover. The etrailer replacement is exactly like the old one and fits perfectly.

This cover didnt work out for me. It does not seal tight and the heat from the summer sun has evaporated the leveling fluid.

Cover and level are holding up and the level is pretty close to true.
