Brownell Boat Stands K4BASE K4 Keel Stand Base Only 16"-24" 20,000 lb SWL

The Brownell Boat Stands K4BASE is a heavy-duty keel stand base designed to safely support vessels during storage and maintenance. Adjustable from 16 to 24 inches in height, this base-only unit serves as a reliable alternative to conventional wood blocks and cribbing, significantly reducing setup time and labor.

Featuring an ACME solid steel threaded top, the K4BASE allows precise height adjustment to ensure a secure, level fit along the keel. Each stand is rated for a Safe Working Load (SWL) of 20,000 lbs (9,100 kg), making it suitable for a wide range of vessel sizes. Keel stands should be spaced evenly along the keel with a minimum of two stands used at a time on a flat, stable surface.

Key Features:

• Adjustable height range: 16" to 24" (41 cm – 61 cm)
• 20,000 lb (9,100 kg) Safe Working Load (SWL) per stand
• ACME solid steel threaded top for precise, tool-free height adjustment

The K4BASE is sold as a base-only unit, ideal for replacing or expanding an existing keel stand setup. Use one keel stand for every 20,000 lbs of vessel weight, spaced evenly along the keel. On softer ground surfaces, a wash plate is recommended under the base for added stability.
