What This Clamp Actually Does
This isn't a hose or a fitting - it's the bracket that holds your air lines and electrical cable in a neat bundle along the frame rail or in the wheel well. Three holes, one clamp, keeps everything from chafing against the chassis or getting caught on debris.
TR075S115 shows up on a wide range of trailers and straight trucks where the OEM ran air lines and 7-way cable together in one path. If your old clamp is cracked, rusted through, or missing altogether (which happens more than you'd think - they vibrate loose), this is a direct replacement.
Material and hole spacing matter here. These clamps aren't universal even though they look simple - the hole diameter has to match your line OD or you'll get rubbing and eventual wear-through, which nobody wants on an air line.
Why These Numbers Cross
The numbers in our interchange table - 022026, 94060, 451038, 17-153 - all reference clamps built to the same three-hole pattern and hole sizing as the 34021. Different manufacturers stamped their own part numbers on essentially the same bracket over the years, which is normal for a piece this basic.
What you want to watch is hole diameter and overall width. If your rig has slightly oversized air lines or a fatter electrical cable jacket, a clamp that crosses on paper might still pinch too tight or leave slack. Pull the old clamp and measure before you order if you don't have the number handy.
Surest way to confirm: check the number stamped on your old clamp if it's still legible, or measure the three hole diameters and overall length. That'll tell you faster than any cross-reference chart whether this one fits your setup.
Ordering From Us
We keep TR075S115 in stock at the Tacoma counter, so if you're local you can grab one same-day and be back on the road. Ship nationwide too if you're not near us - these are light and cheap to send.
At $10 a clamp, it's not worth guessing wrong and paying return shipping. Give us your VIN or the old part number and we'll confirm before it ships.
Comes with our standard 6+ month warranty, though honestly a clamp like this either fits right off the bag or it doesn't - defects are rare but we stand behind it either way.
34021 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 34021. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 34021 fit my Utility trailer?
Depends on how your trailer was set up at the factory - some Utility models ran the triple-hole clamp, others didn't. Give us the VIN or pull your old clamp and check the number stamped on it, and we'll confirm before you order.
Is this the same as the 451038 clamp?
They cross-reference to the same hole pattern and are built for the same bundle of air lines plus electrical cable, but 'same' is a strong word for two different manufacturer part numbers. Confirm by matching hole diameter on your old part - if it lines up, you're good.
My clamp is cracked but I can't read the number anymore - now what?
Measure the three hole diameters and the overall length of the bracket. That's usually enough for us to match it up. If you can snap a photo and send it over, even better - we've seen most of these before.
