What This Door Fits
This is the curbside center access door used on Thermo King Precedent S-600, S-700, and C-600 series reefer units - the panel you pull to get at the condenser/evaporator section on the street side of the box. It's not a universal stamped sheet, it's molded to the Precedent housing dimensions with the factory hinge and latch cutout locations.
98-9641 is the number Thermo King's used most on these across the Precedent lineup, and 98-9121 shows up as an earlier or running-change part number for the same opening. Both are commonly listed on the same units depending on when the reefer was built.
If your unit's still got the old door on it, or a data plate with the model spelled out, that's your fastest way to know you're in the right family before you order.
Why the Numbers Cross - and What to Check
Doors like this get superseded more than you'd think - Thermo King will tweak hinge stock thickness, latch style, or the gasket channel and issue a new number even though the door looks the same from ten feet away. That's likely what's going on between 98-9641 and 98-9121 - same opening, minor running changes.
Before you order, pull the old door (or what's left of it) and check the hinge side - passenger vs driver orientation matters here, and the latch/hasp setup can differ between S-600 and S-700 builds even within the 'same' series. Mounting hole pattern is the other thing to eyeball; if it doesn't line up you'll know in about thirty seconds trying to hang it.
Rule of thumb is always the serial or model tag on the reefer unit itself, not just what somebody told you it was. Precedent units get moved between fleets and re-decked more than you'd expect, so the door on it now isn't always the one it left the factory with.
Ordering From PartStop
We keep DR-012A in stock at the Tacoma counter for guys who need it same day - walk in, match it against your old door or the number on the unit, walk out. If you're not local we ship nationwide and can usually get it out the same afternoon on in-stock orders.
Comes with our standard 6+ month warranty. If something's off on fitment once you get it unboxed, call before you drill or modify anything - we'd rather sort it over the phone than have you stuck with a door that's close but not right.
Give us the unit serial number or a photo of the old door's tag when you call. Saves everybody time versus guessing off the model series alone.

Frequently asked questions
Does 98-9641 fit my Precedent S-700?
Most likely, yes - 98-9641 covers a good chunk of the Precedent lineup including S-700 units, but confirm against your unit's serial tag or the number stamped on the door you're pulling off. Precedent units get parts swapped over the years, so don't assume the door on it now matches what left the factory.
Is this the same as 98-9121?
They're generally treated as interchangeable for this door opening - 98-9121 looks to be an earlier version of the same part before Thermo King updated the number to 98-9641. Function and fit are the same in practice, but if you've got a very old unit, double check hinge orientation before ordering.
Will this door bolt straight on without any modification?
It's built to the factory mounting pattern and hinge location for these Precedent units, so it should hang without cutting or drilling. That said, always verify against your old door or unit VIN first - reefer boxes get field-modified more often than the tractor side, so we can't promise zero surprises on every unit out there.
