Adams Rite 4085-01-IB – Frequently Asked Questions

1) How does the Adams Rite 4085 header bolt work with an MS deadlock on a pair of doors?
The 4085 is the top locking point in a three-point setup. It goes in the active leaf along with an MS pivoted bolt deadlock at the lock stile and a 4015 threshold bolt at the bottom, so one cylinder turn throws security at the header, the stile, and the sill. On its own the header bolt is not a lock, it is the third point that the MS deadlock drives.
2) What length 4085 header bolt do I order for my door height?
The bolt is ordered by Dimension A, the rod run from the deadlock to the header, in four ranges: 30 to 52 inches, 52 to 67 inches, 67 to 79 inches, and 79 to 92 inches. Measure that distance on the actual opening before ordering, because the range you land in is the only thing that changes between them.
3) Will an Adams Rite header bolt still engage if my aluminum doors have sagged or the frame is out of square?
Yes, that is the point of the design. The 3/8 inch hexagonal stainless bolt expands in a scissor action as it rises and centers itself in the strike, so it takes up misalignment instead of jamming against the edge of the strike hole. It is a common reason to pick it on older storefront pairs that have dropped.
4) Does the 4085 header bolt come with a cylinder, and what cylinder does it take?
No cylinder is included in the header bolt itself. The keyed side of the three-point system takes a standard Adams Rite MS cam mortise cylinder, so you order that separately along with your keying. Budget for the cylinder and the 4015 threshold bolt when you price the job.
5) Can I use a 4085 header bolt on a hollow metal or wood pair, or is it aluminum only?
It is engineered first for narrow stile aluminum doors, and hollow metal and wood door options are offered as well. So a storefront pair is the primary application, but the header bolt is not limited to aluminum.
6) Three-point header bolt or a surface flush bolt on the inactive leaf, which should I use on a storefront pair?
A conventional flush bolt secures the inactive leaf only, and someone has to throw it by hand at the door. The 4085 arrangement is different: it is a keyed system where the MS deadlock throws the header bolt and threshold bolt together from the cylinder, so the whole pair locks in one motion at three points. Pick the header bolt when the pair is a main entrance that gets locked and unlocked daily and you want key control; a manual flush bolt is fine on a leaf that stays shut.
7) Can I add access control to a pair of doors using the 4085 header bolt system?
The system works with Adams Rite electric strikes, so the pair can be tied into a card reader or intercom release while the header bolt and threshold bolt keep the mechanical three-point security. Adams Rite is an ASSA ABLOY brand, which is why the electric strike line is designed around these same narrow stile preps.
8) What finishes does the Adams Rite 4085 header bolt come in?
Five: US3 bright brass, US4 satin brass, US10B dark oxidized bronze, US32 bright stainless, and US32D satin stainless. On aluminum storefront most jobs land on US32D to match the existing MS deadlock face and push hardware.
9) Is the Adams Rite 4085 header bolt suitable for commercial buildings and institutional facilities?
It is a commercial product, used on office buildings, schools, healthcare, retail, industrial, multi-tenant residential, and government openings. UL Listed models are offered in the 4085 line, so if a specific opening in your facility calls for a listed assembly, specify the UL model when you order rather than assuming the standard one carries it.
