Don-Jo DCB350 – Frequently Asked Questions

1) Does the Don-Jo DCB-350 mount on the door or on the frame?
The DCB-350 is a strike reinforcement plate, so it goes on the frame at the strike location, not on the door face. It backs up the strike where the latch or bolt lands and where a kick-in load gets concentrated. If what you actually need is protection around the lock bore on the door leaf itself, a wrap-around plate is the part for that job, not a strike reinforcement.
2) How heavy is the steel on the Don-Jo DCB-350 strike reinforcement plate?
16 gauge steel, .060 thick. That is the number that matters on a strike reinforcement: it is the material behind the strike that resists the frame deforming when someone puts a shoulder into the door, and .060 steel is a meaningful step up from the light frame material it is backing. Straight steel construction, so it takes the same paint or coating schedule as the rest of the frame hardware.
3) Is the Don-Jo DCB-350 sold individually or in a bulk pack?
The DCB-350 comes as a shelf pack of 50 plates. That quantity suits the way it usually gets bought: a property manager or facility crew reinforcing every strike on a floor, a contractor stocking a truck for a multi-door job, or a distributor carrying it on the shelf. If you only need to repair one opening, you are still buying the box of 50.
4) Is the Don-Jo DCB-350 meant for commercial doors or will it work on an apartment entry door?
Don-Jo lists the DCB-350 as a commercial part, and it is used on commercial openings including office buildings, schools, healthcare facilities, retail, industrial buildings, government buildings, and multi-tenant residential and apartment properties. Apartment entry doors in a managed building are squarely within that list, so a landlord or REIT hardening unit doors is using it as intended, not stretching it.
5) What is the model number I order for a Don-Jo strike reinforcement plate?
DCB-350 is the Don-Jo designation, written DCB350 on the order line. There is one configuration, so there is no finish, hand, or size choice to make when you specify it. Give a supplier the brand and DCB-350 and you are on the right part.
