<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto"><div>By "zero-offset" Dave does not mean (correct me if I am wrong) a zero-throw triple swivel caster (3 swivel casters mounted to a plate mounted to a bearing), but rather a caster where the wheel bearing/axle (horizontal rotation) is in-line with the bearing/mounting post of the caster body (vertical axis). Making the point of contact between the wheel and the ground inline with the vertical rotation of the caster and eliminating the "throw" you get with a typical swivel caster as the wheel pivots around the mounting. </div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">Brian Munroe <br><br>Sent from a rather small device with big fingers</div><div><br>On Nov 22, 2015, at 8:37 AM, Bill Conner via Stagecraft <<a href="mailto:stagecraft@theatrical.net">stagecraft@theatrical.net</a>> wrote:<br><br></div><blockquote type="cite"><p dir="ltr">Both the plate and the individual swivels? 16 locks?
