501-49 3-Leg Height Adjustable Base

The 501-49 3-Leg Height Adjustable Base from Conset is designed for users who need an L-shaped desk and prefer no lower crossbars between the legs. Elegant and stylish in appearance, a simple touch of a button will raise or lower the entire workstation - offering easy freedom to change working posture throughout the workday. The distinctive tubular leg design enabled the removal of the usual lower traverse crossbar without any sacrifice in the stability of the frame. The result is a clean, contemporary, open design with nothing to interfere with leg movement. Black or silver frame colours are completed with chromed steel telescoping inner legs for a unique look. An expanding upper bracket permits 4" incremental width changes from a minimum of 45.6125" to a maximum width of 69.25" along the main bracket and 53" to 76.625", making the 501-49 versatile enough to accommodate a wide range of table top sizes. For those seeking a quieter unit, the 501-49 is also substantially quieter than most other current Conset bases (i.e. 501-27, etc.).

This design also yields an increased upper range - permitting the frame to elevate from 24.75" to 48.375" at a rate of up to 1.26"/second. The lower range is slightly higher than other frames but at 24.75" is generally acceptable for all except the shortest of users.

Suited for a wide range of table tops, the 20" deep upper bracket supports make the 501-49 ideal for most desktops and lifting up to 198 lbs. It will not, however, work with tops shallower than a nominal 21" depth.
