For faster, more flexible adjustment of your drawer fronts, these Blum Locking Devices are indispensable. They replace the standard locking devices that come with the Blum Tandem Plus Blumotion Drawer Slides (#43841, sold separately), and offer easy tool-free adjustments up and down, and side to side. Just rotate the knob to move the drawer laterally, and press the adjustment tab to move it up and down. The locking devices also make it easy to install and remove your drawers.

  • Captive right device, self-aligning left device-both included
  • Length/Depth can be adjusted using a different screw hole on the slide of the runner (if necessary)

Woodworking Experience:
using Blumotion drawer locks
I love the ease of installing and using the Rockler system. Being able to make adjustments to front drawer position is best way to get perfectly alignment. The handles are very convenient compared to others for pulling and releasing.

Woodworking Experience:
Size limits use
Takes up more space than standard locking device. So in my situation I had to trim the orange plastic a bit. I like the adjustment feature. Recommend use to others.

These are perfectly good Blum Locking...
These are perfectly good Blum Locking Plates. Unfortunately they only fit Tandem slides made in the USA. My stock of ten "slide sets" seem to be original Blum slides made in Austria, and the locking plates shown will not fit.  The slides supplied are now USA made. The Tandem slide system is otherwise great.

Adjustable Drawer locking device for Bluemotion slides
I ordered the newest style and they worked great. I also used the Rockler jig for drilling the alignment holes in the drawer

A little more adjustability...worth a try. WHY WHY WHY do you make us pay for the standard locking device we won't use???
Rick J on Jan 27, 2018
needed to finish customer order.
George Z on Dec 30, 2017
This is the only way to go even though the housing is plastic, the adjustments over the stock device and fit are superior.

Bought the slides and these broke on them. We bought them 09/2012. Don't think they should have broken so quickly.

James F on May 20, 2016
Unfortunately I purchased these because the description on the full extension drawer slides did not indicate that they were included and I thought I had to purchase separately. Fortunately I did because one got broken somehow and voila! I was able to produce another like magic!

How much space do these locks take up?
Ralph H on Aug 20, 2019
BEST ANSWER: These locking devices do not take up a lot of room in the corners of the drawer. They are secured to the bottom of the drawer and out of the way of everything. Make sure you follow the instructions especially for the depth of the drawer rail in order to hide it.
