||GN 31 leveling feet have been designed to meet the requirements of the food industry. Convex bolt head seat on base greatly reduces the formation of deposits and simplifies cleaning.
The rubber underlay is vulcanized into the foot. The adjustable height sleeve shrouds the thread, and can eliminate the
exposure of sharp thread edges.
GN 31 leveling feet have earned the EQUIPMENT ACCEPTANCE CERTIFICATE of the USDA (US-Department of Agriculture).
Static loads specified in the table are based on a series of tests in which a vertical load in relation to the horizontal plane of the foot is applied. If the figures in the table are exceeded, a permanent deformation of the foot can occur.
