Blum TANDEMBOX Bottom Mount Trash Pullout, White, 356M55B7SAB-W

A Purpose-Built Waste and Recycling Pullout for 12-Inch Cabinet Openings

This Blum TANDEMBOX waste and recycle set turns a 12-inch base cabinet opening into a dedicated, smooth-operating refuse station. The complete set delivers the structural sides, runners, and hardware needed to support one or two bins inside a narrow cabinet — keeping waste out of sight and fully accessible with a single pull.

Key Features

• Built for 12-inch cabinet openings — the 12-inch minimum opening width fits standard narrow base cabinets without custom modifications.
• 21-5/8-inch nominal length — sized for a typical kitchen cabinet depth, giving bins full reach out of the cabinet on opening.
• Steel TANDEMBOX construction — engineered steel side profiles carry the load while keeping the profile clean and cabinet-ready.
• White finish — a neutral interior color that reads clean inside painted or white-laminate cabinet boxes.
• Left- and right-hand orientation included — the set covers both sides so no additional handed components are needed to complete the pull-out.
• Bottom-mount configuration — the runners mount beneath the drawer box to keep the full interior width available for bins.

Where This Pull-Out Fits Your Cabinet Layout

Narrow 12-inch base cabinets are one of the most underutilized spaces in a kitchen, often given over to a single roll-out shelf or left as dead storage. A dedicated waste and recycle pull-out reclaims that column for its most practical job. The 21-5/8-inch length suits standard 24-inch-deep base cabinet boxes; the bottom-mount runner keeps the full 12-inch interior width unobstructed so bins drop in cleanly side by side or front to back depending on the bin configuration you choose.

This set suits new construction and renovation work equally well. Cabinet shops building spec kitchens can standardize the waste cabinet on this unit across a run; remodelers retrofitting an existing 12-inch base can install it without modifying the cabinet box.

Construction and Finish

The side profiles are steel, consistent with the TANDEMBOX platform's structural approach. The White finish is a factory-applied color matched to the TANDEMBOX line's interior language — it holds up to the daily contact of bin removal without showing every mark the way bare metal can. The set ships with both left- and right-hand members, so a single order covers one complete pull-out installation.

Bin capacity, bin count, and any included soft-close or door-mount hardware are not stated in the available product data. Confirm those details in the product spec block or with your supplier before specifying bin sizes for the cabinet.

Who Orders This Set

Cabinet shops building production kitchens reach for this set when a 12-inch waste column appears on the plan — the TANDEMBOX platform keeps the job on one system and one supplier. Kitchen designers specifying handle-less or slab-front cabinetry often pair this pull-out with a door-mount kit so the cabinet door carries the bin out with it; the bottom-mount runners are compatible with that configuration. Homeowners renovating a kitchen and keeping an existing 12-inch base cabinet can add this set to upgrade from a freestanding bin to a built-in pull-out without altering the carcass.

A Cleaner Kitchen Starts With the Right Cabinet Hardware

The 12-inch waste and recycle set puts purpose-built Blum TANDEMBOX hardware inside the cabinet column that matters most — turning a narrow, often-overlooked base into the most functional spot in the kitchen.
