Rockwood 557 US26D Manual Flush Bolt
The Rockwood 557 US26D is a corner-mounted flush bolt designed for wood doors, featuring a 1″ x 6-3/4″ face plate and a 3/4″ bolt throw. Its configuration supports door strength with a corner reinforcing plate, a critical factor when reinforcing a door that is expected to maintain integrity during fire-rated performance. The unit is UL approved for wood doors up to 90 minutes, aligning with fire-rated door requirements in many commercial and residential systems. Installation considerations include ensuring proper alignment with the door edge and backset to maintain proper latch alignment in the event of a fire. Material and finish choices can impact durability in high-traffic areas.
CRL Fire Glazing Tape (90 Minute)
CR Laurence’s Fire Glazing Tape is an intumescent glazing tape designed for 90-minute fire-rated assemblies. The tape expands under heat to seal gaps around glazing and frame interfaces, helping to maintain the fire-rating of doors with glass and certain glazing assemblies. It is listed for positive pressure scenarios, which is essential in some building codes where airflow testing is required. When applying, installers should follow the manufacturer’s guidelines for surface preparation, adhesive exposure, and curing times. This product is a critical component in preserving the integrity of fire-rated doors that incorporate glazing.
SOSS 418 Alloy Steel Fire Rated Hinge
The SOSS 418 hinge is designed for fire-rated doors, with a steel construction and a black E-coat exterior finish suitable for exterior or high-traffic interiors. It supports doors from 1-3/4″ to 2″ thick and features a riveted steel hinge pin that is non-removable, which enhances security and stability during heat exposure. The hinge’s moving pivot point helps avoid external pinch points, a helpful safety consideration in renovation projects where door hardware is upgraded to meet fire-rated standards. Proper alignment and secure mounting are essential to ensure consistent operation during an alarm event or fire scenario.
National Door Company ZZ365003 Primed MDF Door Slab
The National Door Company ZZ365003 Primed MDF door slab is a ready-to-paint interior door option with full louver detailing. It measures 24″ x 80″ with typical thickness and is primed for finishing, making it a versatile option for interior fire-rated door assemblies that require a specific look and finish. While primed MDF does not inherently guarantee a fire rating, many interior door assemblies are evaluated in combination with frame and hardware to meet applicable fire-related standards. Consider coordinating with appropriate frame components and glazing seals to maintain any required performance ratings.
LUBANN Solid Alder Interior Door
The LUBANN 32″ x 84″ solid alder interior door offers a premium hardwood option for interior spaces. Unfinished, it provides a customizable foundation for staining or painting to match design schemes. The solid alder construction contributes to a sturdy feel and can be suited for environments where fire-rated doors are specified, though it is crucial to verify the overall door system’s compatibility with fire-rated assemblies, frames, seals, and any glazing components. The included hardware kit supports straightforward installation and integration with existing interior hardware plans.
Buying Guide: Key Considerations For 90 Minute Rated Wood Doors
- Fire-rating requirements: Confirm the door and its components meet the applicable UL or local code requirements for 90-minute protection. Hardware such as flush bolts, hinges, and glazing tapes should carry rated listings for use with fire-rated assemblies.
- Compatibility and integration: Ensure that mortises, backset, and hinge openings align across hardware from different brands. Incompatibilities can compromise the door’s fire performance or functional reliability during an actual event.
- Glazing and seals: When glazing a fire-rated door, select glazing tape and seals designed for high-temperature performance. Proper installation minimizes gaps that could allow flame or smoke penetration.
- Durability and finish: Exterior-facing hardware and hinges should be corrosion-resistant and tested for long-term durability in high-traffic or humid environments, preserving fire-rated performance over time.
- Door construction: For interior doors, solid wood and certain laminates can influence how well a fire-rated door behaves under heat. Consider the synergy between door slab material, core construction, and frame assemblies.
- Installation logistics: Some fire-rated components require precise alignment and professional installation. Verify warranty coverage and installation guidelines to maintain the system’s rating.
- Maintenance: Regular inspection of seals, flush bolts, and hinges helps ensure the door maintains its fire-rated integrity. Replace worn components promptly to prevent performance degradation.
- Code variations: Fire-rating requirements can vary by location. Always consult local codes or a fire protection professional to select the correct rating and compatible hardware.
