This zipper made by TOPAZ INDUSTRIES is designed specially for the heavy duty drysuit.
Please see the below way of the measurement and check the order length(OL) carefully before ordering the zipper
Smart use of zippers :
Close the zipper till the slider completely touches the stop to ensure tightness.
When opening or closing, always ensure that the direction of the pull is along the line of the metal teeth. When closing, ensure that both sides of the open zippers are parallel. It is very important to avoid catching undergarments in the teeth. If the slider should jam during closure, DO NOT FORCE IT. Pull back the slider, remove the obstruction and slowly attempt to close it again.
Excessive force will break the metal chain and destroy the fastener. Also avoid bending the zipper excessively as this will eventually cause the metal chain running inside of the fastener to break.
