Folger Adam 310-4 Sometimes a strike with a ¾" profile just won’t work in a particular application. This is common with aluminum frames or retrofits where the existing roller strike is only ½” high. Any more than ½” profile may require the exit device to be moved and re-installed. Want an easier alternative? The Folger Adam 310-4 faceplate is packaged as a ¾” faceplate so it will work on most installations. However, this faceplate also features a removable shim--which decreases the profile to ½” so it can accommodate installations where a ¾” profile won’t work. The shim can be removed by simply loosening the screws which secure it to the faceplate. Overall, the 310-4 electric strike offers an easier alternative to relocating the exit device.
