Best 90-Minute Fire-Rated Residential Door Hardware and Alternatives
If you need a 90-minute fire-rated residential door, the listed products do not include a complete fire-rated door assembly. The closest match is the KoiLykke concealed closer, described as tested for use on 90-minute doors. The NEWBANG and Boomerang products are fire-rated locks, while the Stealth safes have 90-minute fire protection but are not doors. Use this guide to distinguish the options and identify what to verify before buying.
| Product | Best suited for | What it is |
|---|---|---|
| KoiLykke Concealed Door Closer | Automatic closing on a 90-minute-rated door | Door closer |
| NEWBANG Grade 1 Lock | Keyed commercial-style entry | Door lock |
| Boomerang Privacy Lever | Bathroom privacy function | Door lock |
| Stealth PR23 Safe | Fire protection for stored belongings | Gun safe |
| Stealth PR36 Safe | Greater stated safe capacity | Gun safe |
KoiLykke Concealed Automatic Door Closer
Best for: Buyers who already have a 90-minute fire-rated door and need an automatic closing mechanism. The product listing says it is tested and approved for use on 90-minute fire-rated doors and is designed to close doors without manual intervention.
The tubular closer is concealed within the door and frame, so it avoids visible closer hardware. It is described as suitable for doors up to 50 kg and as providing controlled, soft closing. These details make it the most directly relevant option in this list for a 90-minute door assembly.
Limitation: This is a closer, not a fire-rated door. Confirm that its installation method and door compatibility meet the requirements for your specific assembly.
NEWBANG Grade 1 Keyed Entry Lock
Best for: Buyers seeking a keyed entry lever with a stated fire rating. The listing describes this lock as UL listed for a three-hour fire rating, which is longer than 90 minutes, and identifies it as a Grade 1 commercial lock.
The outside uses a key, while the inside uses a thumb turn. The listing gives a 70 mm (2-3/4-inch) backset and says it fits doors from 1-3/8 to 1-3/4 inches thick. It also states that the lock can be rekeyed and that it satisfies ADA requirements.
Limitation: Check the backset and door thickness before ordering. A fire-rated lock alone does not make a door or opening fire-rated.
Boomerang Commercial Privacy Lever Lock
Best for: Buyers who need a privacy lock for a bathroom or similar interior door and want a product listing that states a fire rating. The lock is described as UL fire-rated for three hours and as ANSI/BHMA A156.2 Grade 2, with a stated rating of over 400,000 cycles.
Its inside push button locks the exterior lever, and turning the interior lever releases the lock. The listing also says the outside can be unlocked with a coin or screwdriver. Heavy-duty construction is intended for frequent use.
Limitation: This is a privacy-function lock, not a keyed entry lock. Confirm that the function and installation requirements suit the door and the intended fire-rated assembly.
Stealth Premier PR23 90-Minute Fire Safe
Best for: Households seeking stated 90-minute fire protection for items stored inside a safe, rather than a fire-rated residential door. The PR23 is listed with a 23-gun capacity, shelves, and a customizable door panel organizer.
Its listed construction includes a 1/4-inch solid steel plate door, 10-gauge steel body and door, and 12 solid steel locking bolts. The listing also describes an electronic lock, a drill-resistant hard plate, and a relocker. It is identified as a UL RSC-rated residential security container.
Limitation: This is a gun safe, not a door or door component. Its fire-protection claim applies to the safe as described in the product listing.
Stealth Premier PR36 90-Minute Fire Safe
Best for: Buyers comparing the Stealth safe options who need the larger model’s stated capacity. The listing describes the PR36 as having a 32-gun capacity and 90-minute fire protection, with shelves and a customizable door panel organizer.
Like the PR23, it is listed with 10-gauge steel construction, a 1/4-inch solid steel plate door, 12 locking bolts, an electronic lock, a hard plate, and a relocker. It is identified as a UL RSC-rated residential security container.
Limitation: The PR36 protects stored contents; it is not a fire-rated residential door. Choose between these safe models based on storage needs, not door-opening requirements.
Buying Guide: What Should You Check Before Choosing?
Are you buying a door, a closer, or a lock?
Start by identifying the part you need. A fire-rated door is not the same as a fire-rated lock, closer, safe, or fireplace door. The products listed here do not include a complete residential door assembly with a stated 90-minute rating. For that requirement, look for a complete, appropriately labeled door assembly and confirm the rating with the supplier or a qualified building professional.
Does the complete assembly need a rating?
Fire performance depends on the specified assembly and its components, not just one piece of hardware. Confirm that the door, frame, hinges, latch, closer, glazing if present, and installation method are permitted for the intended use. Local building requirements can differ, so check the applicable code or ask the authority having jurisdiction.
Which lock function and dimensions fit?
Choose a keyed entry lock for controlled access or a privacy lock for an interior room. Compare the listed backset and door-thickness range with your existing door. Do not assume a lock’s stated fire rating means it is suitable for every fire-rated door.
When is a safe the right choice?
Choose a safe if your goal is fire protection for stored belongings. The Stealth listings state 90-minute fire protection, but neither safe functions as a residential door. Compare capacity and interior organization to select between the PR23 and PR36.
Frequently Asked Questions
Is a 90-minute fire-rated door included in this product list?
No. The list includes door hardware and safes, but it does not provide a complete 90-minute fire-rated residential door.
Can a 90-minute-rated closer make an unrated door fire-rated?
No. A closer is only one component. The door and required components must be suitable as a complete assembly.
Are the NEWBANG and Boomerang locks stated as 90-minute rated?
The listings describe both locks as UL fire-rated for three hours. Verify their suitability for the specific door assembly and application.
Which Stealth safe has the greater listed capacity?
The PR36 is listed for 32 guns, while the PR23 is listed for 23 guns. Both listings state 90-minute fire protection.
What should I verify before installing fire-rated hardware?
Check the door dimensions, hardware function, assembly requirements, installation instructions, and local building rules. Ask a qualified professional when the opening must meet a specific fire rating.
