Hafele Drawer Runners: How to Identify a Drawer Slide and Find a Replacement

If you are replacing a drawer runner, a slide that looks the same may still be the wrong one. A runner is identified by a few printed specifications: mounting, extension, load, nominal length, closing and drawer removal. Below we show where Hafele prints each one, with Matrix examples from our store, so you can compare an old runner with a new one.

Source: Hafele's catalog The Complete Furniture and Cabinetry Hardware (2026 edition), section 8, Drawer Slides. The catalog writes the section first, so page 8.122 is section 8, page 122.

Where Hafele drawer runners are in the catalog

The contents on pages 8.2-8.3 group the section by type of slide. A selection, with the Hafele lines in each group:

• Double-Wall Drawer Systems, pages 8.4-8.38: Matrix Box P Plus, Matrix Box S35 and Matrix Slim Box A (its own pages say thin-wall).
• Concealed Undermount Slides, pages 8.52-8.81: Matrix UM A35 on page 8.78.
• Ball Bearing Slides, pages 8.82-8.127: the Hafele Econo Slide on page 8.122.

In the Matrix drawer set tables on pages 8.8, 8.18-8.20 and 8.27-8.28, the runners are supplied with left and right drawer sides.

1. Mounting: side, undermount or bottom

• Side mount: the ball bearing Econo Slide (8.122), with 12 mm (15/32") side clearance and 45 mm (1-3/4") height.
• Concealed undermount: Matrix UM A35 (8.78) has separate item numbers for 13-16 mm (1/2"-5/8") and 19 mm (3/4") drawer material, and lists front locking clips as required, in four versions with their own item numbers.
• Bottom mount: the epoxy slides on page 8.128.

2. Extension: 3/4, full or overtravel

Matrix Box P Plus, Slim Box A, Box S35, UM A35 and the Econo Slide are all listed as full extension. The epoxy slides are 3/4 extension (8.128). The premium over extension bottom mount slide 423.46.751 is 500 mm (20") installed and 540 mm (21-1/4") extended (8.127).

3. Load class

For the Econo Slide and Matrix UM A35 the catalog prints the capacity per pair: 45 kg (100 lbs.) and 35 kg (75 lb). Slim Box A is listed at 30 kg (66 lbs.) and Box S35 at 35 kg (77 lbs.). Matrix Box P Plus comes in 40 kg (88 lb) and 70 kg (154 lb) classes; in the table on page 8.8 the 40 kg runners run from 270 to 450 mm and the 70 kg runners from 500 to 650 mm.

4. Nominal length, drawer depth and cabinet depth

The Matrix drawer set tables list runners by length, which the drawer system pages call the nominal length (NL). Those pages give the base panel (drawer bottom) and the minimum internal cabinet depth as NL minus or plus a figure that differs by line. In millimeters (the pages also give inches):

The P Plus cabinet depth in the table is for a drawer with door front fixing; for internal drawers page 8.6 gives NL + 21 mm (13/16") with a wood panel and NL + 12 mm (15/32") with an aluminum front panel.

Pages 8.14 and 8.25 also work an example for a 500 mm (19-11/16") runner: internal drawer depth 484 mm (19-1/16") for Slim Box A and 476 mm (18-3/4") for Box S35.

5. Closing: soft close, self-closing, push to open

• Integrated soft close: Matrix Box P Plus, Slim Box A, Box S35 and UM A35.
• Push to open: for Matrix Box P Plus, page 8.8 lists push-to-open soft close unit 513.90.995 for nominal lengths from 350 mm (13-3/4"), with a synchronization rod advised for the touch area.
• Self-closing: the epoxy slides (8.128), the premium over extension slide (8.127) and, together with soft close, Matrix Box P Plus (8.4).

6. Drawer removal and disconnect

• The Econo Slide has a lever disconnect (8.122); our product page for 432.21.983 lists a release lever for removing the running track.

For the steps, follow the installation and removal drawings on pages 8.7, 8.17 and 8.26 and Hafele's installation instructions for your runner.

Reading the Hafele item number

In these tables each length, finish and load class has its own item number (how the numbers are written: our Hafele item numbers guide). Matrix Box P Plus 513.27.702 is the white, 40 kg, 350 mm (13-3/4") version (8.8); our product page lists left and right drawer sides, cabinet runners and cover caps as supplied, front fixing brackets not included.

The Econo Slide table (8.122) has separate numbers for the drawer member, the cabinet member and the pair, in black and zinc. The zinc numbers in the 400 mm (15-3/4") row:

The numbers do not follow one pattern: in the same row the black cabinet member is 432.21.584 and the black pair 432.21.984, while the 450 mm row has 432.21.504 and 432.21.374. Look a number up rather than working it out from a neighboring size. Our product pages call these runners Matrix Runner BB A45; Hafele's catalog lists the same item numbers under the heading Econo Slide. The catalog's Index by Item Number (pages n1-n33) gives the page for a number.

Accuride slides in the Hafele catalog

The overview on pages 8.82-8.83 lists Accuride slides by Accuride type. A selection:

The 7432 table on page 8.102, for example, lists 422.29.955 for a 550 mm (21-5/8") slide. A type number such as 7432 is Accuride's; the eight-digit number is Hafele's. Neither tells you that a slide of another make will fit.

Before you order a replacement

• Mounting, with the side clearance or, for undermount, the drawer material thickness.
• Nominal length and the internal cabinet depth.
• Extension type and load class.
• Closing type.
• How it is sold: a pair, one drawer or cabinet member, or a drawer set with sides.

Measure the old runner and compare each point with the printed specifications of the new one; looking similar is not enough.
