Hey what's up?

So, I bought a tower rack off eBay. This rack is suppose to fit: 2" or 2.25" or 2.5inch wakeboard towers. I have a Zeroflex Tower on my 2001 X-Star... this is a 2" tower! Basically how it works is that they send you a couple different sized rubber inserts that will allow it to fit different sized racks. So with mine, I had to use the thickest rubber insert, plus the additional thin piece of rubber matting they send with it. I have attached a picture and circled the 2 pieces I had to use.

Basically, the tower holds fine until I hit some waves. The jarring of continuously hitting waves slowly makes the tower turn. I have this thing tightened prettty good but it still turns. Is this due to the fact that there are 2 rubber inserts being used? Anyone else had this problem?

I had the same problem with my aftermarket racks for my 99 star. They're a little different than yours, but have the same inserts. I solved the problem by tightening the bolts with a hex head on a rachet instead of an allen wrench. You can get the bolts much tighter. Also, make sure you tighten the bolts evenly so the clamp tightens against the tower evenly. Good luck!

Maybe put a mark on both pieces of rubber to see exactly where it is moving. You could glue the rubber parts together and use rubber cement to between the tower and rubber and rack and rubber. It is not a very good adhesive but it rubs right off with your finger so may be worth a shot. Otherwise, I think you are on to more permanent, non-reversable fixes.

Rereading my post makes me wonder about the following. What if you taped off and plasticoated (plasti-dip) the tower and rack where they join? If it doesn't work it seems to peal off, so once again, it is completely reversible and worth a shot.

Try some duct tape between the rubbers and the rubber and the tower. You can add extra to make it incramentaly thicker as needed. Just make sure you cover it all up with the clamp so you don't look like a redneck out there.

I had a similar problem but i just wrapped my tower (where the rack was mounted) with that rubbery tape that only sticks to itself. has held solid for 4 seasons.

Isn't your tower 1 7/8" instead of 2"? I am pretty sure that is the case. But either way, what wakerpunk said above should do the trick.

Those are some awesome ideas, thanks guys! I'm going to try some of those things and we'll see what works!

Wakereviews, you might be right about it being 1 7/8 inches. We simply took a measuring tape and eye-balled it at 2 inches. This is my first time buying a wakeboard rack so... lesson learned i guess!

Wakerpunk, what is this "rubbery tape" you're talking about? Can you send post a picture, or a link or something??

This is the link to the site of where I bought the tape.

I actually found some double-sided adhesive tape called "Rhino Grip". I'm going to give this a shot and see how it works out. Thanks again!!

I am pretty sure it is 1-7/8" as well.

Greg, go measure your tower again. Here's how, for those without a calipers (hopefully this will help others as well):

Take a piece of string and wrap it around your tower leg to measure the circumference. Then measure the string with a tape measure. (If you have a craft tape measure, you can measure directly.)

Now, take that measurement and divide it by 3.14 to get the diameter of your tower leg.

For a 1-7/8" tower, your string should measure about 5-7/8" (5.875 / 3.14 = 1.87")
For a 2" tower, your string should measure about 6-1/4" (6.25 / 3.14 = 2")

Drill and tap for a set screw? Unless you don't want to scar your tower.

Hey again. So I measured it this morning with string. It measured just under 6 inches. So yeah, it looks like it is 1 and 7/8.

I tried that RhinoGrip double-sided adhesive tape. It worked to keep the two rubber pieces together, but the rubber is still sliding on the pole.

I'm thinking at this point maybe the best thing to do is see if I can get a 1 and 7/8 rubber fitting off the internet. I thought about tapping a screw but... I don't think I want to do that.

Good luck with that. i have been battling it for years and have tried everything in the book.
Think or compare to handlebars on a BMX bike. The job is quite the same and how well would rubber inserts work there?

The conclusion I came up with is to buy the correct racks that fit the tube size without rubber spacers.

IMO nothing else besides a screw or welder is ever really going to work.

I'm in the same boat. A pair of racks that don't fit. So much for a good deal.

It's interesting that you wrote that. I just contacted the guy I bought the boat off of and asked him what he used. He told me that he used a rack that was designed for 1 and 7/8 inches with no rubber inserts. The rack he used was just metal to metal contact. He said it worked great!

I have 2" racks on a 1 7/8" tower. I used clear rubber tubing from home depot to fill the gap. Works great.

Hey man. Any chance you could post a link? I'm lookin around on the home depot site right now.

Anyone think I'd be better off with something like this??

I had that problem one time when I purchased wrong size clamps. I went to home depot purchased a section of 1" aluminium strip metal. Cut two pieces to fit on the inside of the clamp and formed to match the curve of the tower. You have to make sure both pieces fall short of the overall circle length so the clamp can bolt down all the way. I bolted the clamp on the tower with no rubber inserts. Never once came loose.

I used a small torch and a pin hammer to form the aluminum strip i needed.

This may be the most redneck thing ever but it cost me about $15 for the piece of aluminum and about 1 hour to make them work. I hope i made since.

Your tower is 100% and 1 7/8 100%

Why not bypass the Jerry rigged nonsense and it looks like te clamp is a universal style bolt patter. Go to and buy an 1 7/8 clamp. Problem solved

Xstarrider, I'm not sure what you mean by "your tower is 100%". But anyways, yeah I actually contacted DIY-wake today. Their clamp is a little different than mine. Their clamps use bolts that insert from the inside of the clamp to secure itself to the rack. This is kinda of reverse design to what mine is. I'm trying to get a hold of a company called bullet-lines. They might have a clamp that will work with my rack. Hopefully I know the answer to this by tomorrow.

Thanks to everyone for their suggestions!

The only thing that bugs about NOT using a rubber insert is that I'm afraid the metal-to-metal contact might blemish the tower a little bit. Not a big deal in the long run I guess though.

Sorry just meant it is 100% an 1 7/8 dam iPhone and its small screen.

boardjnky4, not sure what clear plumbing stuff you're talking about. Any more info?

Well... looks like claims that their tower clamps will work with my rack. I emailed them pictures! So, looks like I should get this by the end of this work, or early next week. I ordered the 1 and 7/8. I hope it works!
