The Bobrick B-3588.MBLK is the matte black version of the TrimLineSeries™ surface-mounted multi-roll toilet tissue dispenser — a two-roll, theft-resistant unit that keeps a second roll in reserve while the first is in use. Built from heavy-gauge Type-304 stainless steel with a matte black finish and all-welded construction, the B-3588.MBLK fits the same matte black hardware program as the rest of Bobrick's Matte Black Collection. As a Bobrick Premier Partner, Total Restroom carries the B-3588.MBLK with a Low Price Guarantee.

Key Features

Two-Roll Reserve System

The B-3588.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 skirt and door are also Type-304 stainless in the same matte black finish. The matte black finish coordinates with the rest of Bobrick's Matte Black Collection for facilities specifying matte black hardware throughout the washroom.

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.

Surface or Recessed Installation

The B-3588.MBLK is designed as a surface-mounted dispenser. The skirt is removable in the field for optional recessed mounting where wall depth, framing, and project conditions allow.

ADA-Compliant When Properly Installed

Bobrick's recommended mounting height for ADA installations is 22-3/8" (570mm) above the finished floor, measured to the operable part (bottom of the dispenser opening). For ICC, the recommended height is 25-3/8" (640mm) AFF; for California Building Code (CBC), it's 26-3/8" (670mm) 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-3588 is sold in two finishes from the same TrimLineSeries™ family. The B-3588.MBLK — this product — has a matte black finish over Type-304 stainless steel. The Bobrick B-3588 in satin-finish stainless steel is the standard finish version, identical in dimensions, capacity, and operation. Choose based on the finish that matches the rest of your washroom hardware — matte black for designer or contemporary specifications, satin stainless for traditional commercial restrooms.

How Many Do You Need?

Plan one B-3588.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-3588.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.

Can the B-3588.MBLK be recessed into the wall?

Yes. The mounting skirt is removable in the field, allowing the unit to be converted from surface-mounted to recessed installation. The recessed install requires sufficient wall depth and may need additional framing depending on the wall construction.

Is the B-3588.MBLK ADA compliant?

The B-3588.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 22-3/8" (570mm) 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-3588.MBLK?

Bobrick offers individual replacement parts for the B-3588 family, including the Spindle (3588-33), the matte-black-specific Skirt Kit (3588.MBLK-53), 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 dimensions of the B-3588.MBLK?

The dispenser measures 13-11/16" wide by 8-1/2" tall by 4-5/8" deep (345 x 215 x 115 mm). It projects 4-5/8" from the wall when surface-mounted.

Is mounting hardware included?

No — fasteners are not furnished. The installer chooses appropriate hardware based on wall construction. For partitions with particleboard or solid core, Bobrick recommends four #10 x 5/8" sheet-metal screws or through-bolts. For plaster, drywall, or hollow walls, options include sheet-metal screws into concealed backing, fiber plugs and expansion shields, or 3/16" toggle bolts.

What is the difference between the B-3588 and B-3588.MBLK?

Both are the same TrimLineSeries™ multi-roll toilet tissue dispenser, with identical dimensions, capacity, lock, and operation. The B-3588 has a satin-finish stainless steel body; the B-3588.MBLK has a matte black finish over the Type-304 stainless body. Choose based on the finish that fits your washroom design.
