Product Description

We've always received a ton of calls to make Interlocking Inner Diameter Tube Clamps/Couplers. When we sat down to come up with a design, we thought we could greatly improve upon what already existed. We built a number of unique features into these that sets them apart! At TMR Customs we manufacture the world's best roll cage clamp!

1: Both bolts can be loaded from the same direction! Gone are the days of threading in one fastener from the front side, and one fastener from the back side. Now you can mount our tube clamp extremely close to other components on your chassis without interference issues!

2: Locking feature - we use a nylon lock nut. No need to worry about stripping out the tapped holes in your clamps. The nylock nuts key into the machined pocket, eliminating the need to hold them with a wrench or socket when tightening. 

3: We machined a large 45 degree chamfer along the interlocking edges. This makes it much easier to align the clamps, especially after they have pulled from welding, or the tubes have slightly tweaked from a roll over or crash.

4: We left enough length on the small ID that is inserted into the tube that you can properly plug weld these for additional strength.

Used these to make a 6 point cage removable so I could do powdercoating on it. They work awesome, awesome machining and good fits. I wish they were cheaper because 6 adds up, but in the end definitely worth the price. I masked off the areas I painted to make sure it all still fit good after paint. (Posted on 10/19/2017)

Product Q&A

Are these NHRA legal for a 6 point cage to use for removable door bars?
Hi Vince,

Our recommendation would be to contact NHRA or a local racing body to confirm legality.

Do the 1-1/2” fit .120 wall pipe?
Hi Jeff. Please choose the 1.5" Outside Diameter and 1.25" Inside Diameter. They will be a perfect fit for your 1.5" x .120"W material. Thanks!
Hi Regarding the measurements given for these couplings, what is the outer number for and what are the inner number for? Im in search for couplings that fit a 1 1/2" inner diamet pipe. /Johan
Hi Johan. The measurements must match the tube sized used in your roll cage. Outside Diameter is the OD of your tubing, Inside Diameter is the ID of your tubing.
Is the price listed for a set of 2 or individually?
Hi Brandon. The Tube Clamps are sold individually, as pictured. Hope that helps!
