What This Twistlock Actually Is
This is the locking mechanism used on extendable chassis - the kind that stretches out to haul containers of different lengths. The twistlock engages into the frame rail holes and locks the extension in place so the chassis doesn't telescope on the road. Great Dane and CIMC both used this style across a long production run, 2000 through current.
It's not a universal grab-and-go part. There are different handle lengths, different lock head diameters, and different mounting brackets depending on how the manufacturer built that particular frame. Some units bolt straight to the rail, others use a bracket that's welded on.
If your old one is worn out, seized, or the handle's bent from being run over by a chain or dropped trailer, that's usually your sign to replace rather than fight with it.
Reading the Cross-Reference Numbers
The numbers in the table - 1402-2274, HF-005, 1402-6373, 6202-5020-C/D, 1103-1213 - cross because different suppliers packaged the same basic twistlock design under their own part numbers over the years. Great Dane and CIMC both sourced from a handful of manufacturers, so you'll see overlap between what shows up in a Great Dane parts book versus a CIMC one.
What actually matters when you're matching these up: the lock head diameter (needs to seat in your frame rail hole), the handle/arm length (short arm vs long arm changes how much clearance you've got when it's in the unlocked position), and the mounting hole pattern on the bracket. A C/D suffix like on 6202-5020 usually means there's a left-hand and right-hand version - don't grab the wrong side.
Surest way to confirm: pull the old twistlock off, read whatever number's stamped or cast into it, and match that against the table. If it's rusted past reading, measure the lock head and bracket bolt pattern and call us with those numbers plus your VIN.
Ordering From PartStop
We stock this in Tacoma and pull same-day for local fleets and owner-operators who need a chassis back in service instead of sitting in the yard. Ship nationwide if you're not local - most orders get out the same or next business day.
At $96.50 this isn't the kind of part you want to guess on twice. Comes with our 6+ month warranty, so if something's off with the fit or it fails early, we take care of it.
Give us the VIN or the numbers off the old twistlock before you order. We'd rather spend two minutes confirming than have you shipping a wrong-side lock back to us.
TWISTLOCK Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to TWISTLOCK. 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 6202-5020-C/D fit my 2015 Great Dane extendable chassis?
Likely, but confirm before ordering - the C/D suffix means there's a handed pair (left/right), so check your VIN or pull the old unit's number to make sure you're getting the correct side and matching lock head diameter for your specific chassis.
Is this the same as the HF-005 twistlock?
HF-005 cross-references to the same design family used across Great Dane and CIMC builds in this era, but 'same as' still means match the lock head size and arm length against your old part - don't just order by brand name alone.
My chassis extension is hard to lock, is it the twistlock or something else?
Could be either - worn twistlock components, bent alignment pins on the frame rail, or debris in the extension rails can all cause a hard lock. Pull the twistlock and check for wear on the lock head and handle pivot before you replace it; if the frame rail holes themselves are elongated, that's a bigger repair.
