Roller runners, ball-bearing with soft-close, Blum Tandembox, Hettich InnoTech — what the difference is, what it costs, and what to choose for a kitchen.
Types of Drawer Runners
Drawer quality is determined less by the box material and more by the runner type. This is the component you touch several times a day.
Roller Runners
The most budget option. The drawer rides on two rollers at the bottom that run on steel tracks. Mounted underneath the drawer box.
- Partial extension: the drawer opens to about 75% of its depth — the back stays in shadow
- No soft-close: you push the drawer shut by hand all the way
- Load capacity: 15–25 kg
- Lateral play — the drawer wobbles slightly at full extension
- Rollers wear over time; squeaking develops
- Price: low; found in entry-level furniture
Ball-Bearing Runners with Full Extension
Steel runners with a ball-bearing cage, mounted on the sides of the drawer box.
- Full extension: the drawer opens to 100% of its depth — everything inside is accessible
- Smooth action with minimal play
- Load capacity: 25–45 kg depending on model
- Soft-close: optional (integrated or as a separate add-on module)
- A damper can be added separately if not included
- Price: mid-range; standard in most mid-segment kitchens
Metal Drawer Systems (Blum Tandembox, Hettich InnoTech)
All-in-one systems: metal side panels and runners in a single module. The drawer box is built around the sides rather than placed on top of them.
- Full extension with integrated soft-close (Blumotion / Silent System)
- Steel or aluminium sides: slim, rigid, and warp-free
- Load capacity: 40–70 kg (Blum Tandembox Antaro rated to 70 kg)
- Built-in three-axis adjustment without tools
- Push-to-open or locking options available
- Internal dividers and organiser systems are standard accessories
- Price: upper-mid to high

What Full Extension Actually Means
With partial extension (roller runners) the rear third of the drawer stays inside the cabinet. In a 500 mm deep kitchen drawer that is 150 mm of inaccessible space — where spoons, lids, and bags disappear and can only be retrieved by bending down and reaching in. Full extension is not a comfort feature; it is basic ergonomics.
Soft-Close: Necessary or Not
- Soft-close pulls the drawer in over the last 30–50 mm — no need to push it home
- No slamming — relevant at night and with children
- Ball-bearing runners without soft-close need careful closing; over time the box starts banging against the back panel
- On metal systems soft-close is integrated and adjustable for closing force
- On ball-bearing runners it is either built in from the start or added as a separate damper clip
What to Choose
- Budget furniture for a dacha or temporary use — roller runners are sufficient
- Mid-range kitchen — ball-bearing runners with full extension and soft-close, rated at least 35 kg
- A kitchen built to last — Blum Tandembox or Hettich InnoTech: serviceability, adjustment, longevity
- Heavy drawers (crockery, cleaning supplies) — a metal drawer system is essential
A quick quality check: pull the drawer fully open and push sideways on one corner. A good runner gives no movement. A roller runner will always have some play.
