Frequently Asked Questions

Question: My desk work station is 22" deep. Here it states the Ergotron WorkFit-T needs 24" deep. Will this still work with my desk? Answer: If your desk is only 22" deep than 2" of the platform will hang over your desk, note that this can also affect the sturdiness. Are you using single monitor or dual? <a href="/product_info.php?products_id=16977">WorkFit-S</a> could work for you as well and you only need 17" deep desk:
