Key Features

Two-Roll Reserve System

The B-35883.MBLK holds two standard-core toilet tissue rolls up to 5-1/8" (130mm) diameter — 1,500 sheets per roll. While one roll is in use, the second roll stays in reserve, helping reduce run-outs between maintenance checks. The dispenser does not accept jumbo or junior-jumbo rolls.

Matte Black Finish Over Type-304 Stainless

The cabinet is 18-8, Type-304 heavy-gauge stainless steel with all-welded construction, finished in matte black. The door is also Type-304 stainless in the same matte black finish. The matte black coordinates with the rest of Bobrick's Matte Black Collection for facilities specifying matte black hardware throughout the washroom.

Recessed Installation, Low Profile

The B-35883.MBLK is designed as a recessed dispenser, mounted into a framed rough wall opening of 12-1/2" W x 7-3/8" H with at least 4" of wall depth behind. The cabinet projects only 1-1/8" from the finish face of the wall, giving the unit a flush, low-profile appearance. Coordinate with the mechanical engineer to avoid pipes, vents, and conduits behind the rough opening.

Theft-Resistant Lock and Spindle

A tumbler lock sits flush with the door — no protrusion — and is keyed like other Bobrick washroom accessories, so the same Bobrick key type may work across compatible Bobrick washroom accessories. The spindle is 18-gauge, 1" diameter Type-304 stainless tubing with plastic end caps, theft resistant and removable only with the key provided.

ADA-Compliant When Properly Installed

Bobrick's recommended mounting height for ADA installations is 21-1/2" (550mm) above the finished floor, measured to the operable part (bottom of the dispenser opening). For ICC, the recommended height is 24-1/2" (620mm) AFF; for California Building Code (CBC), it's 25-1/2" (650mm) AFF. Minimum operable-part heights are 15" (381mm) AFF for ADA, 18" (457mm) AFF for ICC, and 19" (483mm) AFF for CBC.

Which Version Is Right for You?

The B-35883 is available in two finishes from the same TrimLineSeries™ family. The B-35883.MBLK — this product — has a matte black finish over Type-304 stainless steel. The Bobrick B-35883 in satin-finish stainless steel is the same recessed dispenser with a satin stainless finish, identical in dimensions, capacity, and operation. If you need surface-mounted instead of recessed, see the Bobrick B-3588.MBLK — the same matte black multi-roll tissue dispenser in a surface-mounted configuration with a full skirt.

How Many Do You Need?

Plan one B-35883.MBLK per stall for facilities that have specified matte black hardware throughout the washroom. The two-roll capacity is the main reason maintenance teams choose this style — one roll in use, one in reserve.

Frequently Asked Questions

What size toilet tissue rolls does the Bobrick B-35883.MBLK hold?

The dispenser holds two standard-core toilet tissue rolls up to 5-1/8" (130mm) in diameter, 1,500 sheets per roll. It does not accept jumbo or junior-jumbo rolls — the unit is sized specifically for standard-core toilet tissue rolls.

What rough wall opening do I need for the B-35883.MBLK?

Frame a rough wall opening of 12-1/2" wide x 7-3/8" high (318 x 187 mm), with a minimum 4" (102 mm) of recessed depth behind the wall. Coordinate with the mechanical engineer to avoid pipes, vents, and conduits in the wall cavity, and allow clearance for any construction features that may protrude into the rough opening from the opposite wall.

Is the B-35883.MBLK ADA compliant?

The B-35883.MBLK can be installed to meet ADA accessibility requirements when the operable part (bottom of the dispenser opening) is at least 15" (381mm) above the finished floor. Bobrick's recommended ADA mounting height is 21-1/2" (550mm) AFF. ICC and California Building Code (CBC) have higher minimums — 18" and 19" respectively.

Is the lock keyed the same as other Bobrick dispensers?

Yes. The flush-mounted tumbler lock is keyed like other Bobrick washroom accessories, so the same Bobrick key type may work across compatible Bobrick washroom accessories. Replacement lock and key kits (Bobrick part 388-42) are available through Total Restroom if a key is lost.

What replacement parts are available for the B-35883.MBLK?

Bobrick offers individual replacement parts for the B-35883 family, including the Spindle (3588-33), the Door Replacement Kit (3588-173), and the Lock and Key (388-42). Total Restroom can order any of these parts for you.

What are the exact cabinet dimensions of the B-35883.MBLK?

The cabinet measures 13-5/8" wide by 8-7/16" tall (346 x 215 mm) and projects 1-1/8" (30 mm) from the finish face of the wall when properly recessed. The required rough wall opening is 12-1/2" W x 7-3/8" H with a minimum 4" recessed depth.

Is mounting hardware included?

No — fasteners are not furnished. Per Bobrick's installation instructions, secure the cabinet with (4) #10 x 1-1/4" sheet-metal screws at the points marked "S" on the spec sheet, with shims between the framing and cabinet as needed. The installer chooses appropriate hardware based on wall framing and substrate.

What is the difference between the B-35883 and B-35883.MBLK?

Both are the same TrimLineSeries™ recessed multi-roll toilet tissue dispenser, with identical dimensions, rough wall opening, capacity, lock, and operation. The B-35883 has a satin-finish stainless steel body; the B-35883.MBLK has a matte black finish over the Type-304 stainless body. Choose based on the finish that fits your washroom design.
