CoreLift Double frame technical data
Who this frame is for
You have two tabletops. Existing, made to measure or by a joiner — the frame adapts to their length.
You are refitting workstations. Unscrew the tabletops from the old frame and screw them onto the sit-stand one. Two fixed facing desks become sit-stand desks.
You are running a project. In an office refit the tabletops stay and only the frames are replaced.
You are an architect or planner. DWG files and project prices are available — write to sales@heka-interior.com.

Frequently asked questions
Are the tabletops included?
No. You buy only the frame for two desks — the lifting frame with four motors, two memory controllers, power supply and fixings. You bring your own tabletops. If you want the complete desk with tabletops, choose the CoreLift Double sit-stand desk.
Which tabletops fit this frame?
The frame of each desk is telescopic and you set it between 102 and 180 cm, both sides the same. On the CoreLift Double desk we fit tabletops 120–180 cm long and 70, 75 or 80 cm deep. If you are not sure whether your tabletops fit, send us the dimensions at sales@heka-interior.com and we will check.
Can I keep the tabletops of my existing desks?
Yes. If the tabletops are in good condition and within 102–180 cm, unscrew them from the old frame and screw them onto the sit-stand one. Two fixed desks become sit-stand desks.
How does assembly work?
In three steps: set the frame length of each desk, screw the tabletops onto the frame, then fit a controller under the front edge of each desk and connect the motors and power supply. Instructions are included.
What is the warranty?
3 years. The warranty covers the motors, the lifting mechanism and material defects. We provide spare parts also after the warranty ends.
Do you offer discounts for larger quantities or projects?
Yes. Volume discounts from 5 units up. For office refits where the existing tabletops stay we prepare a dedicated quote. Send an inquiry or call +386 1 361 90 28.
