NDC 101-LH – Frequently Asked Questions

1) Can I convert an old offset concealed floor closer to a surface closer without pulling the floor check out of the slab?
That's exactly what the NDC 101 retrofit kit is for. Instead of cutting out the original floor closer, patching the floor, and hanging the door on a continuous hinge with a surface mounted closer, the kit lets you leave the floor check in place and work with a surface-mounted closer above. On a job where the concrete is finished, terrazzo, or tile, that's the difference between a hardware swap and a floor repair.
2) Which offset do I need, the 3/4 inch or the 1.5 inch NDC 101 kit?
NDC offers the 101 retrofit kit in a 3/4 inch offset and a 1.5 inch offset, and the one you need is set by the offset arm on the floor check already in the door. The 3/4 inch kit is the 3/4 inch offset version. Measure the existing offset before ordering, because the two are not interchangeable on the same opening.
3) Does the NDC 101 retrofit kit work on Rixon-Duronatic floor checks?
Rixon-Duronatic floor checks are named specifically. NDC's retrofit kits convert floor checks with 1.5 inch offset arms to surface-mounted closers on that make, so if you are looking at a Rixon-Duronatic in the slab, the kit is built for it.
4) Do I have to order the NDC 101 offset retrofit kit left hand or right hand?
Handing is a required choice. The 101 kit comes as a left hand or a right hand assembly, so you specify the hand of the door before it ships. Stand outside the opening (the pull side of the door as you approach it): if the hinges are on your left, it's left hand. Getting this wrong on a floor closer retrofit means the arm geometry won't pick up the door.
5) Is the NDC 101 kit a complete closer, or do I still need to buy a surface closer?
The 101 is a retrofit kit, not a door closer. It's the hardware that adapts an existing offset floor check to accept a surface-mounted closer, so the surface closer itself is a separate order. Plan the job as two line items: this kit in the correct offset and handing, plus the surface closer you want on the head.
6) Will an NDC 101 retrofit kit hold a heavy institutional entrance door?
The 101 uses a bronze casting rated by NDC to hold normal through heavyweight institutional doors. That covers the traffic you see in schools, hospitals, courthouses, and municipal buildings, which is the usual place these old offset floor checks are still in service.
7) Is the NDC 101 offset retrofit kit meant for commercial openings or will it work on a house?
Commercial. NDC classes the 101 as commercial door hardware, and it's aimed at buildings with concealed offset floor checks already in the slab, which is a commercial and institutional condition rather than a residential one.
