Match the seat-mechanism socket, base taper and installed seat-height range.
Match a chair gas-lift column by its complete dimensions, taper interfaces and release geometry. Compare published column references for swivel chairs and seating, then send the part code and quantity.
Matching product family: Chair gas-lift columns →

Provides controlled seat-height adjustment through the release button and seat lever. It is a dedicated column, not an ordinary eye-to-eye lid support.
Match the seat-mechanism socket, base taper and installed seat-height range.
Different column heights and adjustment ranges need their own matching dimensions.
Identify the complete column; a similar tube diameter alone does not confirm fit.
Use the original marking or a drawing wherever possible. Measurements may be supplied in millimeters or inches.
Original code, complete column photo and the source drawing if available.
Extended length L, outer tube length B, taper position C and both tube diameters.
Required adjustment and installed seat height; do not equate travel with total chair height.
Seat/base taper details, release button/lever interface and order quantity.
A published spring extension force is not an occupant weight rating. Column stroke and the source seat-adjustment range can also differ.
Choose a reference and include your quantity. Each record keeps its original dimensional scope and a link to the source.
Published application references help identify your request. They are not Horizon stock codes. Confirm the exact assembly, fittings and quantity in your quotation. Unpublished specifications are left open for matching.
Match full column, taper position, seat/base interfaces and release mechanism; stroke differs from the published seat adjustment range.
