Bobrick 290-2436.MBLK (24 x 36) 290, Welded-Frame Mirrors, Matte Black, 24"W x 36"H

24" x 36" Mirrors | Bobrick Matte Black Collection | Bobrick B-290 Series

Public restrooms commonly specify wall mirrors above lavatory stations — and most facilities choose a framed, commercial-grade unit instead of a residential-style mirror because commercial construction holds up to daily cleaning, tampering, and long-term moisture exposure. The Bobrick B-290 2436.MBLK is a 24" W x 36" H welded-frame mirror built around a one-piece Type-304 stainless steel angle frame with a powder-coated matte black finish, mounted to a concealed wall hanger / bracket system designed to keep the mirror secured against the wall. As a Bobrick Premier Partner, Total Restroom stocks the B-290.MBLK series with Low Price Guarantee and 48-Hour QuickShip on in-stock sizes.

Key Features

Powder-Coated Matte Black Finish

The B-290 2436.MBLK frame is Type-304 stainless steel finished with a powder-coated matte black coating — part of Bobrick's Matte Black Collection of coordinating washroom accessories. Matte black hides fingerprints and minor water spots better than polished finishes and integrates with contemporary restroom designs that pair black hardware with darker surfaces, exposed concrete, or warm-tone tile. Type-304 stainless underneath the powder coat is better suited to commercial cleaning and high-moisture restroom environments than many residential-style mirror frames.

One-Piece Welded Stainless Frame

The B-290 frame is roll-formed from a single 3/4" x 3/4" Type-304 stainless steel angle. Corners are heliarc welded, then ground and polished smooth before the matte black powder coat is applied — there are no exposed seams or fasteners on the frame, and the powder coat covers a uniform welded base.

Concealed Wall Hanger / Bracket System

The B-290 2436.MBLK mounts to a concealed wall hanger / bracket system designed to keep the mirror secured against the wall. At 24" wide, the B-290 2436.MBLK uses Bobrick's "2S" tab design (per Bobrick's tech data sheet, the 2S tab design applies to B-290 mirrors up to 36" width). An upper bracket engages the upper louver on the mirror's backplate, and the lower bracket is secured to the back of the mirror with double-sided tape after the mirror is pressed into final position. The result is a clean, fastener-free front face — no visible mounting hardware on the frame in a finished restroom.

15-Year Silver Spoilage Warranty

The 1/4" (6 mm) No. 1 quality select float glass mirror is electrolytically copper-plated by the galvanic process and warranted by Bobrick for 15 years against silver spoilage — the gradual edge corrosion and black-spotting that ruins lower-grade mirrors in humid environments. The mirror back is protected by full-size 3/16" shock-absorbing polyethylene padding, and all edges are protected by plastic filler strips.

Which Size Is Right for You?

The B-290 2436.MBLK (24" W x 36" H) is part of the full B-290.MBLK matte black welded-frame series, available in seven sizes:

• B-290 1830.MBLK — 18" W x 30" H — smaller restrooms or above narrow vanities
• B-290 1836.MBLK — 18" W x 36" H — taller framing in narrow spaces
• B-290 2430.MBLK — 24" W x 30" H — shorter profile at standard 24" width
• B-290 2436.MBLK — 24" W x 36" H — this size
• B-290 2448.MBLK — 24" W x 48" H — taller mirror for full upper-body view
• B-290 2460.MBLK — 24" W x 60" H — full-length above-counter installations
• B-290 2472.MBLK — 24" W x 72" H — full-length installations

If your project calls for a satin-finish stainless steel frame instead of matte black, the same mirror is available in B-290 satin finish — same frame profile, same construction, same sizes. For tempered glass (schools, healthcare, areas with potential impact), look at the Bobrick B-2908 series — same welded frame, tempered glass instead of standard float glass.

Installation & ADA Compliance

Under ADA Standards §603.3, mirrors located above lavatories or countertops must be installed with the bottom edge of the reflecting surface no higher than 40" (1015 mm) above the finished floor. Mirrors not located above lavatories must be installed with the bottom edge no higher than 35" (890 mm) AFF. The B-290.MBLK can be used in ADA-compliant restroom layouts when installed at the required mounting height — the product's suitability for accessible restroom layouts depends on proper installation height and project requirements; mounting height is the installer's responsibility.

For installation of the B-290 2436.MBLK, Bobrick's "2S" tab design requires 5-3/8" (137 mm) clearance above the centerline of the mounting screw holes (so the mirror can be lifted onto the wall hanger), plus 1" (25 mm) minimum clearance at the bottom. Provide concealed wall backing to comply with local building codes; mounting screws are not furnished and should be selected based on the wall substrate.

Frequently Asked Questions

What are the actual dimensions of the B-290 2436.MBLK?

The Bobrick B-290 2436.MBLK measures 24" W x 36" H (61 x 91 cm) outside-of-frame to outside-of-frame. The frame itself is a one-piece 3/4" x 3/4" (19 x 19 mm) Type-304 stainless steel angle with a matte black powder-coated finish. Bobrick's stated manufacturing tolerance on B-290 mirrors is ± 1/8" (3.2 mm).

Is the B-290 2436.MBLK ADA-compliant?

The B-290 2436.MBLK can be used in ADA-compliant restroom layouts when installed at the required mounting height. ADA §603.3 requires that mirrors above lavatories be mounted with the bottom of the reflecting surface no higher than 40" (1015 mm) above the finished floor; mirrors not above lavatories no higher than 35" (890 mm) AFF. The product's suitability for accessible restroom layouts depends on proper installation height and project requirements; mounting height is set during installation.

How does the matte black finish hold up in a commercial restroom?

The matte black finish is a powder coat applied over Type-304 stainless steel. Powder coating bonds chemically to the metal substrate and is better suited to high-traffic commercial cleaning than painted or chrome-plated finishes. Matte black also hides fingerprints and water spots better than polished finishes between cleaning cycles.

What is the silver spoilage warranty on the B-290.MBLK mirror?

Bobrick warrants the B-290.MBLK mirror's reflective surface for 15 years against silver spoilage. The mirror is No. 1 quality 1/4" (6 mm) select float glass, electrolytically copper-plated by the galvanic process, with edge protection from plastic filler strips and a full-size 3/16" polyethylene back pad.

Is the B-290.MBLK mirror tempered or standard glass?

The B-290.MBLK uses standard 1/4" (6 mm) No. 1 quality select float glass — not tempered. For installations that require tempered glass, Bobrick offers the B-2908 series welded-frame mirror, which uses 1/4" tempered glass in the same Type-304 stainless welded frame.

How does the B-290.MBLK mount to the wall?

The B-290 2436.MBLK mounts to a concealed wall hanger / bracket system. Bobrick's "2S" tab design uses an upper bracket that engages the upper louver, with the lower bracket secured using double-sided tape after the mirror is pressed into final position. Mounting screws are not furnished and should be selected based on the wall substrate.

Does the B-290 2436.MBLK come with mounting screws?

No. Mounting screws are not furnished with the B-290.MBLK — the appropriate fasteners depend on the wall substrate. For drywall or plaster, provide concealed wall backing per local building codes and use screws sized to the backing. For other wall surfaces, use fiber plugs, expansion shields, 1/8" toggle bolts, or expansion bolts as appropriate.

How fast does the Bobrick B-290 2436.MBLK ship?

Total Restroom stocks the B-290 2436.MBLK with 48-Hour QuickShip availability on in-stock units, shipped from a national distribution network.
