Frequently Asked Questions
Which specific stands is this handknob compatible with?
This replacement fits the Ultimate Support TS-30, TS-33, LT-88B, LT-99B, and LT-99BL stands. Verify your stand model before ordering — the shaft diameter and thread pitch are specific to these models and may not match other Ultimate Support stands outside this list.
How difficult is it to swap in this replacement knob?
Straightforward. The handknob threads onto the existing shaft on the stand's locking collar — no tools required for installation. The process takes under two minutes if the old knob has fully stripped or broken free.
What does the 1.37" shaft length affect?
The shaft length determines how much thread engagement you get when tightening the collar. The 35mm shaft on this knob matches the original part geometry, ensuring the locking collar clamps down with the same clamping force as the factory knob.
Can I use any generic handknob as a replacement?
Not reliably. Thread pitch and shaft diameter are specific to these stands. A generic knob that looks similar may not engage the threads properly, leading to incomplete locking or cross-threading that damages the stand's collar.
