Video Transcript for Hopkins Bulls Eye Surface Level Review

Today we'll be taking a look at the Hopkins Bullseye Surface Level, part number HN09815. This multi-purpose surface level's a great way to ensure accuracy, with the indicator displaying a level plane right in the middle of the bulls-eye. The level itself is an inch and three-quarter diameter. It's got clear liquid with a white background to ensure good contrast. We'll be going over some features of the level. I'll go ahead and show you how to get it installed. The first thing we need to do is make sure that our trailer is level front to back and side to side.

Here on the side of our trailer, we'll need to find a fixed point. We're going to go off the top of our trim right here with our carpenter's level. As you can see, we're slightly out of level front to back. We're going to have a buddy go out front and lower our trailer. Yep, that's good. With the front and back taken care of, we're going to go ahead and level our our side to side.

We're going to come up here to the A-frame of our trailer. With the level on our A-frame, you can see that our side to side is slightly out of level. We'll go ahead and have a buddy adjust our stabilizers. Little bit more. There it is. With our trailer level front to back and side to side, we can go ahead and take our new Hopkins Bullseye Surface Level and place it down on top of our coupler.

For a more permanent solution offers three holes so you can attach it to your surface. You will need to provide your own hardware. That's going to complete our look of the Hopkins Bullseye Surface Level, part number HN09815. .

What can I say, bubble levels. Came quick, standard shape. I'll tell you in 3 or 4 years how they hold up to the Arizona sun. 271112


Still alive, but I keep it covered when not traveling. Seems to be lasting Ok...

Fit the "emergency" handle hole in my electric trailer jack. I'm not sure what brand the jack is as the labeling long ago sun bleached. It is the same jack as shown in a photo by another reviewer. The only thing I had to do was enlarge the 3 screw holes in the level. Unfortunately one of those holes cracked when I tightened down the screw as when the jack manufacturer mounted the original level they didn't remove the drill filings and I missed one. Not this level's fault. I did check the level's "true" with a good carpenters level and it was right on. We'll see how long it lasts before the bubble expands to the point it is useless. The original level lasted 3 years. Therefore my rating is 5 stars "so far". 713980

Perfect replacement for the bubble level that came on my Winnebago MicroMini Travel Trailer's 12V Tongue Jack (RAM 3500lb Electric A Frame Jack) became as big as the inside diameter of the level bulb, rendering it useless. I searched the web and found these on etrailer.com. I ordered two because they were so well priced and the shipping was the same amount for 2 as it was for 1. Now I have a spare. Note. Does not come with screws. The screw three holes were slightly smaller than the the one I was replacing so I reamed the hole with a scratch awl (a small nail would work - or a drill bit) so the original screws would fit. The three holes were in the exact poitions to fit the jack mounting cap. 435380

The bubble level that I bought looks like it is well made, however, I will have to drill new holes in my Airstream tongue jack to install it since there is no exact replacement available. The new one is larger than the original. 322642

  • Bubble Level Replacement Recommendation for an Atwood A-Frame Jack
  • I have a great solution for you, but Atwood does not have a replacement part for their bubble levels on their jacks like the part # AT81068. Instead you would want the part # HM09516. Or for one more similar to what came on the jack you would want the part # HM09815. I attached an install video for you to check out.

  • How To Add A Bubble Level To An Electric Trailer Jack
  • I do have an option for you but the Replacement Manual Override Cover with Level part # 2500-3755E is not a universal part, it is designed specifically for the Stromberg Carlson Electric Trailer Jack part # JET-3755. Therefore, I cannot confirm it will work with your Fastec Electric Trailer Jack (FIC). That said, if you are just looking to add a bubble level then you can use the Hopkins Bull's Eye Surface Level part # HM09815. You can either use some self-tapping screws or double sided...
