材料与表面处理 | 低碳钢，表面硬化，镀锌，络酸盐夹保护层或不锈钢 |
如何指定 | 1. 确定外门板和门框厚度： 外门板P= 门框厚度= 2. 选择搭扣 3. 选择挡圈款式 4. 使用所选搭扣和挡圈，从表格中选择正确的常量 5. 将外面板厚度（P、）门框厚度（F）和步骤4中找出的常量加在一起，来确定被锁物的总厚度（TMT） TMT=P+F+常量 6. 在零件号表格第一栏给定的范围中找出TMT值 7. 确保外面板厚度(P)不超过第二栏中给定的值，这可确保挡圈正确安装在最后的螺纹上面并可将螺钉固定到外面板上 8. 查阅零件号表格，选择合适您所需头型的梁零件号 |
附注 | 工具头型钥匙另外订购 零件号：EV200-01010001 |
对于全缩回型螺钉，B必须小于门框厚度和搭扣高度的总和 | |
