Adams Rite 4505-17-121 – Frequently Asked Questions

1) Will the Adams Rite 4505-17-121 strike work with my MS1850 deadlock, or only the MS+1890?
The 4505-17-121 box strike is configured for the Adams Rite MS+1890 Series lockset, in a center hung door application with a 4 inch jamb. That combination (MS+1890, center hung, 4 inch jamb) is what the part number covers. If your opening runs a different Adams Rite deadlock or an offset/butt hung arrangement, you want the 4505 variant built for that condition instead, not this one.
2) Can a Kwikset or Emtek deadbolt strike plate be used in place of the Adams Rite 4505-17-121 on an aluminum storefront door?
No. The 4505-17-121 is a flat long lip box strike built for Adams Rite MS+1890 Series locksets in a center hung door with a 4 inch jamb, so the lip length and box depth are matched to that hookbolt/deadbolt throw and jamb condition. The Emtek 83223 is a standard deadbolt strike plate with square corners and the Kwikset 81640 is a strike box, both of which are residential-pattern deadbolt hardware for wood-frame door prep rather than aluminum jamb prep. Use the Adams Rite strike when the opening is an MS+1890 installation.
3) What does "flat long lip" mean on an Adams Rite box strike, and when do I need the long lip version?
Flat means the strike face is not raised or beveled, so it sits flush in the jamb prep. The long lip extends the strike lip further out past the frame face, which is what a center hung door needs because the bolt crosses more of the gap between door and jamb. On a 4 inch jamb with a center hung leaf, the long lip carries the bolt to the box. A short lip strike in the same opening leaves the bolt unsupported at the edge.
4) Is this an OEM Adams Rite part or an aftermarket strike?
Genuine Adams Rite, sold as a replacement part for the 4505 strike family, model 4505-17-121. It's the factory strike for MS+1890 installations, so the bolt engagement and jamb prep match the original hardware rather than requiring you to re-cut the frame.
5) Will the Rite Coat Dark Bronze finish match my existing dark bronze storefront hardware?
Rite Coat Dark Bronze is Adams Rite's own factory coating, so it's the finish to order when the MS+1890 lock, handles and door rails on the opening are already Adams Rite dark bronze. It's a coated finish rather than plated, applied for corrosion resistance on exterior commercial doors. If the rest of the opening is aluminum clear or a painted bronze from another maker, expect a close rather than exact visual match.
6) Do I need a separate strike box, or is the box part of the 4505-17-121?
It's a box strike, so the enclosure that receives the bolt is part of the unit. You are not adding a separate dust box the way you would with a residential setup, where a Kwikset 81640 strike box or 81231-001 metal dust box is bought alongside the plate.
7) We manage several storefront entrances. Is this the right part to standardize on for repeat MS+1890 repairs?
For openings that are all center hung with a 4 inch jamb and MS+1890 locks in dark bronze, yes, 4505-17-121 is the single part to stock. Where jamb depth or hanging method varies across your doors, the 4505 series is broken out by those conditions, so survey each opening before buying in quantity rather than assuming one number covers the fleet.
8) What strike should I use if the jamb prep is not fixed and I need adjustment to line up the bolt?
The Adams Rite 4505-17-121 is a fixed flat long lip box strike dimensioned for a center hung door with a 4 inch jamb, so alignment is set by the MS+1890 prep. If the opening needs latitude at the strike, the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a 6 way adjustable deadlatch, both deadbolt strike plate function. Those are adjustment-oriented parts for conventional door prep, not Adams Rite storefront replacements.
9) I only need the dust box behind the strike, not a full strike plate. What is the difference?
The Adams Rite 4505-17-121 is a complete box strike, meaning the lipped face plate and the bolt pocket are one part for the MS+1890 Series. The Kwikset 81231-001 is a metal strike dust box on its own, which is the pocket component used behind a separate face plate. If the existing Adams Rite face plate is damaged or the jamb condition is the center hung 4 inch jamb, the 4505-17-121 is the part that restores the whole strike.
10) Is the Codelocks ASA strike plate an equivalent to the Adams Rite 4505-17-121?
They are not interchangeable. The Codelocks ASA strike plate is an ASA-pattern strike in a stainless steel finish, which is the standard ANSI cutout used with cylindrical and mortise lock prep. The Adams Rite 4505-17-121 is a flat long lip box strike finished in Rite Coat Dark Bronze and dimensioned for MS+1890 Series locksets in a center hung door with a 4 inch jamb. Match the strike to the lock body and jamb prep already in the opening.
