Drawer box for Blum MOVENTO 763: sizes, notch and hook holes

MOVENTO is Blum’s premium undermount runner, with the smoothest motion and the widest weight range Blum builds for a wood drawer box. This page covers the 763H, the frameless 763., the heavy duty 769., and TIP-ON BLUMOTION push to open, with the exact numbers so the box you order drops onto the runners you already have.

Quick answer. A Blum MOVENTO 763 box needs 1/2 to 5/8 in sides, an inside width of opening minus 42 mm (1 21/32 in), a length equal to the runner’s nominal length, and a 50 mm (1 15/16 in) by 13 mm (1/2 in) rear notch with a 6 mm hook hole. With TIP-ON BLUMOTION push to open the notch widens to 125 mm (4 15/16 in). Tell us your exact model and we match it.

Blum publishes a static rating only for MOVENTO, no dynamic figure. All three take the same drawer box; the 769. simply runs longer and rates higher, and 18 to 30 in boxes on a 769. need the cabinet sides blocked out rather than mounted to a face frame.

REAR NOTCH, EACH BOTTOM CORNER50 mm (1 15/16 in) minimum wide, 13 mm (1/2 in) tall. 125 mm (4 15/16 in) wide with TIP-ON BLUMOTION.
REAR HOOK HOLE6 mm diameter, 10 mm deep, 7 mm (9/32 in) in from the inside face of the side, 11 mm (7/16 in) above the notch, the same position TANDEM uses
CLIP PRE-BOREtwo holes, 2.5 mm diameter, 10 mm deep at 75 degrees, 24 mm along the front and 23 mm along the side from the inside front corner

The clip pre bore is the one dimension that is not shared with TANDEM 563: MOVENTO’s holes sit 23 mm along the side from the front corner, versus 32 mm on a 563. A box drilled for TANDEM clips is mis-drilled for MOVENTO clips, and the reverse, so always tell us which runner the box is for even if the width and notch look the same. These numbers come from Blum’s own MOVENTO brochure and the MOVENTO drawer preparation and installation differences sheet.

About the MOVENTO slide

MOVENTO is Blum’s full extension undermount runner with BLUMOTION soft close built in, and it is the only Blum wood drawer runner sold with TIP-ON BLUMOTION push to open in Blum’s US line, which also supports SERVO-DRIVE. MOVENTO is a different runner from TANDEM, not a tier of it: it has its own motion, its own depth templates, and its own clip pre bore, so a box built for one is not automatically correct for the other even though the width rule looks identical.

To identify a MOVENTO runner, pull the drawer and read the print near the back of the metal: “763H,” “763.” or “769.” with a length code. The metric equivalents 760H and 766H use the same drawer box and notch.

Clips: do we install one, do we sell one?

Blum T51.7601 Clips on our configurator adds the standard left and right locking devices for $5.99, installed before shipping. T51.7601 adjusts 1.5 mm side to side and 3 mm in height, and needs at least 6 11/16 in of inside drawer width. It is never interchangeable with a TANDEM T51.1901 clip.

Lengths and depths we build for MOVENTO

Depth has to equal the runner’s nominal length exactly. 12 to 21 in covers 763H and 763.; 24 to 30 in only exists as the 769.

A worked example

Say your cabinet opening is 21 in wide, the runner reads “763H,” and you want our standard 5/8 in sides. Outside width is 21 in minus 10 mm (13/32 in), which is 20 19/32 in. Depth matches the 21 in runner exactly. The opening is 11 1/2 in tall, so a 10 5/8 in box height stays under the opening minus 29/32 in rule. On the configurator: Notching “Notched & Drilled For Undermount Slides,” Slide Brand/Model “Blum MOVENTO 763,” Clips “Blum T51.7601 Clips,” Depth Selection “21” Inches (D),” width 20 19/32 in, height 10 5/8 in. For TIP-ON push to open on that same opening, choose “Other or unlisted slide model” instead and type “MOVENTO with TIP-ON BLUMOTION” so the 125 mm notch is cut.

Keep your slides or replace them?

Keep the runners almost always. MOVENTO is built for heavy, daily use and rarely wears out before the box does; if it still glides and the BLUMOTION soft close still catches, replace only the box. The soft close lives in the runner, not the box, so reusing your MOVENTO runners keeps the exact motion you had.

Measure in three steps: read the model and length off the runner, measure the old box to the 1/32 in if you still have it, or measure the cabinet opening and runner length if you do not. The full steps are in how to measure, and how to install undermount drawer slides covers dropping the new box on.

Common mistakes

  • Ordering the 35 mm TANDEM notch for a MOVENTO box. MOVENTO needs 50 mm, or 125 mm with TIP-ON.
  • Adding TIP-ON onto a box already cut to the 50 mm notch. TIP-ON needs the 125 mm notch from the start; order a new box with TIP-ON specified rather than trying to add it to one already built.
  • Ordering 3/4 in sides. MOVENTO is not rated for them.
  • Using TANDEM’s T51.1901 clip. MOVENTO’s pre bore sits 23 mm along the side, not 32 mm; the clips and the pre bore are both different.
  • Using a metric “NL minus 10 mm” rule meant for European catalogs. US box length equals the runner’s nominal length.
  • Box too tall for the opening. MOVENTO needs 29/32 in of clearance, not the 25/32 in some generic guides use.

How to order a MOVENTO box from Gritly

1. Notching

Choose Notched & Drilled For Undermount Slides. The notch and drilling are free.

2. Slide brand and model

Choose Blum MOVENTO 763. This cuts the standard 50 mm notch and covers 763H, 763. and 769. For TIP-ON, choose Other or unlisted slide model and type “MOVENTO with TIP-ON BLUMOTION.”

3. Clips

Blum T51.7601 Clips adds the standard pair for $5.99. Need the narrow or vertical device instead? Choose No Clips and buy it separately.

4. Depth

Match the runner length exactly: 12, 15, 18, 21, 24, 27 or 30 in.

5. Width

Enter the outside width: opening minus 13/32 in for 5/8 in sides, minus 5/8 in for 1/2 in sides.

6. Height and bottom

Stay under the opening minus 29/32 in. The bottom recess is cut to 1/2 in with either the 1/4 in or the 1/2 in bottom.

Questions

Is Blum MOVENTO the same as TANDEM?

No. Both are Blum undermount runners, but MOVENTO is the higher end runner with a different motion, its own depth templates and a different clip pre bore. A box built for TANDEM is not automatically right for MOVENTO.

Do I keep my MOVENTO soft close when replacing the drawer?

Yes. The soft close is in the MOVENTO runner, not the box. Reusing your runners keeps the exact motion you had; we build only the box they carry.

What notch does MOVENTO need?

50 mm (1 15/16 in) minimum wide by 13 mm tall for the standard runner, widening to 125 mm (4 15/16 in) with TIP-ON BLUMOTION push to open.

Does MOVENTO come in 30 in?

Yes, as the 769. heavy duty runner, rated 170 lb static. 763H and 763. top out at 21 in; 18 to 30 in boxes on a 769. need the cabinet sides blocked out.

Which clip fits MOVENTO?

T51.7601, the standard left and right device, which is our configurator’s Blum T51.7601 Clips option. It is never interchangeable with TANDEM’s T51.1901.

Can I add TIP-ON to my MOVENTO drawer later?

Not to an existing box. TIP-ON needs a 125 mm rear notch cut from the start; a box already cut to the standard 50 mm notch is too narrow. Order a new box with TIP-ON specified if you want to add it.
