Frequently Asked Questions

Question: I have an IKEA Galant desk top surface. Will this work as a top for this base? It is within the max top dimensions given, but I am wondering how thick the top has to be for the screws. Answer: It looks like the desk will work. For this base, the length of the top surface should be between 41"-72" and the width should be between 23.5"-30.5". The thickness should be between 0.80”-1.75.”
Question: It appears that this WorkFit-B is not motor driven. There appears to be a handbrake. Release the handbrake and it moves. Is this correct? In that case, is it counter-balanced? What happens if you have a heavy load, say 88 lbs, and you release the brake? Thud?? Do you have models like this (base only) that are motor driven? Answer: Yes, this unit is not motor-driven and it does have a handbrake. Release the brake and it can be moved up and down. The unit moves with a coiled spring technology. When you release the brake with a full load (88lbs) the unit will maintain its position and can be moved up or down using your hand with very little effort. We do have models available with built-in motors and push button control. One of them is the WorkRite Sierra HX Rectangular Height Adjustable Table, which can be purchased base only.
