GENERAL

This category covers fire door hardware intended for use with composite (steel-covered only) hollow-metal, sheet-metal, and tin-clad fire doors. These doors are usually prepared for a specific set of hardware on the job site.

To provide the degree of fire protection to a wall opening as indicated by the fire door label, this hardware must be applied and the resulting door hardware assembly installed in accordance with the recommendations in ANSI/NFPA 80, "Fire Doors and Other Opening Protectives."

This hardware is of two types: hardware intended for use with sliding doors, and hardware intended for use with swinging doors.

Sliding Type

Hardware for horizontally sliding composite (steel-covered) and hollow-metal doors, and horizontally and vertically sliding sheet-metal doors, is essentially the same as for tin-clad doors, with minor differences to conform to the constructions of various manufacturers.

Hardware for horizontally sliding tin-clad, sheet-metal, and hollow-metal doors, mounted singly or center parting, and single-sliding composite (steel-covered) doors is designed for openings not exceeding 120 sq ft with no dimension exceeding 12 ft.

Each complete set of certified hardware for horizontally single-slide tin-clad doors contains: (1) One track, length equal to twice the width of the opening plus 21 in., punched for wall bolts. (2) Two hangers for openings 6 ft and less in width; three hangers for openings wider than 6 ft; and bolts for attaching hanger to door. (3) Two front binders for openings 8 ft and less in height; three front binders for openings higher than 8 ft; one rear binder and binder pocket for openings 10 ft and less in height; two rear binders and binder pockets for openings higher than 10 ft. (4) One stay roll with attachment bolts suitable for the form of sill used. (5) One bracket for each track bolt. (6) Two half oval chafing strips for back of door; two flat strips for front of door opposite half oval strips; bolts for fastening above strips together through door; length of strips to be 4 in. less than width of door. Doors exceeding 8 ft in height require three chafing strip assemblies. (7) One strip 5 in. less than width of door to take wear of stay roll; and wood screws for attachment. (8) One wedge with screws for attachment. (9) Handles with bolts and screws for attachment. (10) One front bumper and one back bumper. (11) Four bumper shoes and screws for attachment; each bumper shoe may be made in two pieces. (12) Washers for all wall bolts. (13) Instructions for installation.

Hardware for vertically sliding tin-clad and sheet-metal doors is designed for openings not exceeding 80 sq ft in area, with no dimension exceeding 12 ft.

Each complete set of certified hardware for vertically sliding tin-clad and sheet-metal door contains: (1) Two 3-1/2 by 3/8 in. tracks, length equal to twice the height of the opening plus 9 in. punched for wall bolts. (2) One cast iron bracket for each track bolt. (3) Two malleable iron track guides for each track for openings 5 ft or less in height and an additional guide for each track for each 2-1/2 ft or fraction thereof in excess of 5 ft. (4) One bumper bolted to top of each track with wall bolt. (5) Four bumper shoes and screws for attachment. (6) Two wrought-iron or steel cables, not less than 5/16-in. diameter. (7) Two cable brackets. (8) Four cable fasteners and thimbles. (9) Two cable pulleys, with malleable iron frames and sheaves. (10) Counterweights. (11) Two 3/4 by 1/4 in. half oval chafing strips for back of door; length 2 in. less than height of door; strips held by 1/4 in. bolts or machine screws with countersunk heads, passing through door and bearing against washers. (12) Handles with bolts and screws for attachment. (13) Necessary washers, rivets, bolts, and screws to properly fasten the hardware to the door and wall. (14) Instructions for installation.

Certification Marks are applied to each hanger, binder, bumper, flush pull, stay roll, and to each section of track in a set of certified single-slide hardware, and for center-parting doors, Certification Marks are applied to each track section, center floor binder, center track binder, and center latch assembly.

Swinging Type

Swinging hardware is designed for single-swing sheet-metal and three-ply tin-clad doors not exceeding 6 ft in width and 12 ft in height and doors swinging in pairs not exceeding 10 ft in width and 12 ft in height and two-ply tin-clad doors swinging single not exceeding 6 ft in width and 10 ft in height and doors swinging in pairs not exceeding 10 ft in width and 10 ft in height.

Each complete set of certified hardware for single-swing door includes wall strips (except for openings supplied with standard steel frames), hinge brackets, hinges, catches, latches, latch keepers, connecting bar, operating handle mechanism, latch spring, and necessary washers, rivets, and bolts to mount hardware on door and wall. For doors mounted in pairs — above members, top and bottom bolts and top and bottom bolt keepers for standing doors.

Hardware for sheet-metal doors is essentially the same as tin-clad doors with minor differences to conform to the door construction of various manufacturers.

Certification Marks are applied to each hinge strap, hinge bracket, connecting bar, and catch for single doors, and for doors in pairs, also to each latch, each top and bottom bolt and keeper for the standing door, and to each hinge wall strap.
