Adams Rite® Expanding Header Bolt Kit — Door Hardware Replacement

• Expanding top bolt
• Inactive door lock for paired doors

CRL Adams Rite® 4085 Header Bolt (SKU: AR408503) adds a secure top-of-door locking point for the inactive leaf of a paired door when used with the DL2110B or MS18533 long-throw deadlock. The expanding bolt deploys in a scissors action as the MS pivoted bolt triggers it, centering itself in the strike as it rises for reliable engagement.

Fits these door height → cylinder height combinations:

• Door 84" (2.13 m) or less — Cylinder 32" to 53" (813 to 1346 mm)
• Door 85" to 90" (2.16 to 2.29 m) — Cylinder 38" to 59" (965 to 1499 mm)
• Door 91" to 96" (2.31 to 2.44 m) — Cylinder 44" to 64" (1120 to 1630 mm)
