Baldwin Estate 8098000DC03 Double Cylinder Conversion Kit for 2" - 2-1/4" Door

It converts a Baldwin Estate Series deadbolt to double cylinder operation, meaning a key is required from both the inside and the outside instead of a thumbturn on the interior. It's a parts kit, not a complete lock, so you're adding the conversion hardware to an existing Estate Series deadbolt rather than buying a new lock body.

No. This kit is sized specifically for doors measuring 2 inches to 2-1/4 inches thick. A 1-3/4 inch door, which is the standard commercial and most common exterior residential thickness, needs the conversion kit built for that thinner range. Measure the door edge before ordering, because the tailpiece and screw lengths in a thick-door kit will not seat correctly on a thinner door.

That's exactly the case this kit is built for. The 8098000DC03 covers the 2 inch to 2-1/4 inch door range, which is where a lot of custom and solid wood entry doors land, and it swaps the interior thumbturn side of a Baldwin Estate Series deadbolt over to key operation. Anything outside that thickness range needs a different kit.

Baldwin catalogs the Estate Series 8098000DC03 as residential hardware. For a commercial opening, a multi-family corridor, or anything under a code-driven spec, you want a Grade 1 or Grade 2 commercial deadbolt rather than an Estate Series conversion. The kit itself is steel, so durability isn't the issue; the application classification is.

A double cylinder is what people reach for when there's glass in or beside the door, since a thumbturn within arm's reach of a broken pane can be turned from outside. The tradeoff is egress: with both sides keyed, nobody leaves through that door without a key, and many residential codes restrict double cylinder deadbolts on required exits for exactly that reason. If the door is a primary exit, keep the thumbturn and address the glass another way. If it's a secondary door with a sidelite, the conversion makes sense.

You need the deadbolt already. The 8098000DC03 is a conversion kit of parts that changes how an existing Baldwin Estate Series deadbolt operates on the interior side; it isn't a standalone lockset. If you're starting from a bare door with no bolt in it, order a complete double cylinder deadbolt instead of this kit.

Measure the door thickness at the edge, at the bolt location. The 8098000DC03 is the one option here and it covers 2 inches through 2-1/4 inches. There's a single size offered on it, so if your measurement falls outside that window this isn't the right part number. Doors with heavy weatherstripping or an applied panel can measure thicker than they look, so measure the slab itself rather than assuming.
