Because the Simple Switch Machine is direct acting, I only require 4 mm or less of motion. The spring that goes up into the throwbar provides some compliance and pressure against the stock rails if the actual distance travelled is less than 4 mm.<br /><br />The small E3s are available in either zinc or stainless steel. For simplicity, we can look at two head styles available in black zinc from Amazon:<br /><br />1. For the winghead, search for "Southco E3-57-15". Look around for the best price and availability by changing the 1 to any number between 1 and 8. This digit denotes the grip range with the included cam, but we won't need that part so it becomes irrelevant.<br /><br />2. For the tubular key, search for "Southco E3-55-X5", where X can be any number between 1 and 8. You'll also need the key, so search for "E3-26-819-15".<br /><br />You can go for a chrome finish by changing the last digit "5" to a "1", i.e. E3-57-11, or splurge and go with stainless by changing the last digit to a 2.<br /><br />Good luck!<br /><br />Robin TalukdarRobin Talukdarhttps://www.blogger.com/profile/03304581635289062962noreply@blogger.comtag:blogger.com,1999:blog-3193352040666599330.post-79893549364927179492016-01-25T13:58:30.969-05:002016-01-25T13:58:30.969-05:00Need some additonal product info on the cam latche...Need some additonal product info on the cam latches being used.
