Adams Rite 26-0203-03 – Frequently Asked Questions

1) What door thickness does the Adams Rite 26-0203-03 thick door kit cover?
The 26-0203-03 kit covers doors from 2.75 inches to 3 inches thick. That's well past the 1-3/4 inch standard commercial door, so this is the part you order when a standard spindle won't reach through the door and engage the lever. If your door is under 2.75 inches, this kit is the wrong length.
2) Will the 26-0203-03 spindle kit work with an Adams Rite lever other than the 4568?
It's built for the Adams Rite 4568 lever handle. The spindle geometry is matched to that handle, so treat it as a 4568 part rather than a universal thick-door spindle. If your opening uses a different Adams Rite lever, order the thick door kit called out for that lever.
3) Is the Adams Rite 26-0203-03 a complete deadlatch, or just the spindle hardware?
It's a replacement parts kit, not a lock. You get the thick door spindle hardware that lets a 4568 lever engage an Adams Rite Eurostyle deadlatch through an oversized door. The deadlatch itself and the lever handle are separate purchases.
4) Can a Deltana drive-in latch be used in place of the Adams Rite 26-0203-03 on a thick commercial door?
No. The Adams Rite 26-0203-03 is a spindle and thick door kit that extends the drive through a door measuring 2.75 inch to 3 inch thick so an Adams Rite 4568 lever handle stays engaged with a Eurostyle deadlatch. The Deltana DLE23875 is a drive-in latch with an entry function, and its listed door thickness range is 1-3/8 inch to 2 inch, so it is a latch body for standard residential-weight doors rather than a spindle for an oversized commercial door. The two parts do not do the same job, and the Deltana range stops well short of the thickness the 26-0203-03 is made for.
5) My storefront lever feels loose and won't retract the latch. Is a thick door spindle kit the fix?
If the door is between 2.75 and 3 inches thick and someone installed a standard-length spindle, yes, that's a common cause. A short spindle doesn't get full engagement into the 4568 lever, so the handle turns with slop or fails to pull the deadlatch back. The 26-0203-03 supplies the extended spindle reach for that thickness range. If the door is standard thickness, look at the latch or the lever set instead.
6) I'm standardizing hardware across a building with mixed door thicknesses. Do I need the 26-0203-03 on every opening?
Only on the openings measuring 2.75 to 3 inches thick. The rest of the doors take the standard-length spindle supplied with the 4568 lever. Measure each leaf before you order; it's common in a portfolio to have a handful of thick entry doors and the balance at normal thickness, and the kits are not interchangeable in either direction.
7) I need a fire-rated latch, not a spindle kit. Is there an alternative to the Adams Rite 26-0203-03?
The 26-0203-03 is a replacement spindle and thick door kit for an Adams Rite 4568 lever handle, so it carries no latch function of its own. If the opening actually calls for a fire-rated latch body, the Kwikset 83518 is an adjustable square drive UL 3 hour latch, and the Kwikset 83521 is a plain latch UL 3 hour intended for BBL, KNL, CNL and PLL trim. Those are cylindrical lock latches, not Eurostyle deadlatch components, so confirm which lock is in the door before ordering.
8) Is the Kwikset 84290 plainlatch an equivalent replacement part for an Adams Rite Eurostyle deadlatch?
No. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset, a cylindrical latch that drops into a bored door prep. The Adams Rite 26-0203-03 is a spindle and thick door kit that mates a 4568 lever handle to a Eurostyle deadlatch across a 2.75 inch to 3 inch door. They address different lock architectures, and the Kwikset latch will not engage Adams Rite Eurostyle deadlatch trim.
9) Is the Adams Rite 26-0203-03 kit rated for commercial door traffic or is it a residential part?
Commercial. Adams Rite classifies the 26-0203-03 as commercial hardware, and it's aimed at storefront, office, institutional and industrial entries where the door assembly is thicker than normal.
10) How do I make sure I'm ordering the right Adams Rite thick door kit?
Match three things: the model number 26-0203-03, the 4568 lever handle it's cut for, and a measured door thickness between 2.75 and 3 inches. Adams Rite runs several thick door kits with similar part numbers, so order by the full number rather than by description.
