McKinney T4A3782 6 in Half Surface Heavy Weight Hinge

Institutional Grade Features & Benefits

• Half surface. Five-knuckle heavy-weight hinge. The jamb leaf fastens into the mortise. The door leaf is applied to the face of the door with thru-bolts and grommet nuts. Per the catalog heavy half-surface page.
• Size. 6 in (152.4 mm). Gauge 0.203 in. Per the catalog page.
• Material. Steel. Square corner. Heavy weight. ANSI A8411. NRP is standard: the pin is held by an NRP set screw, so the hinge is reversible.
• Listing. Approved for NFPA 80 fire-rated openings on that catalog page. For high-frequency or heavy wood or metal doors.
• Fasteners. 10 holes. Door (2) 1/4-20 thru-bolts and grommet nuts. Jamb 1/2 in x 1/4-20 machine screws. The page packs machine screws, thru-bolts, and grommet nuts. The 6 in row says to advise whether the door is 1-3/4 in or 2-1/4 in so the packed bolt is the right length.
• Factory options (not priced here). BP-10 back plate, TB ball bearing, hospital tip. This page does not list QC or CC.
• Document. The catalog page is on the Documents tab. McKinney has not published a separate mill template on this page, so none is attached. The half-mortise mill is a different prep.
