滑动玻璃门 3D模型

A free 3d model of a  SLIDING GLASS DOOR. Sliding glass doors present a major security problem if they do not have the proper locks and if special steps are not taken to prevent removal of the door. A sliding glass door is lifted into position when installed and, therefore, must be lifted from the track to be removed. To prevent this, it is recommended that 1 1/4 inch pan head (large head), sheet metal screws be inserted into the top of the door frame at both ends and at the middle. These screws should be adjusted so that the door barely clears them when it is operated. 　 The best lock for a sliding glass door is a deadlock, which utilizes a bore pin tumbler cylinder and is operated by a key from the outside. The lock bolt should engage the strike sufficiently so that it will not be disengaged by any amount of movement. When the existing inside pull has to be changed in order to accommodate a new deadlock, an inside cylinder pull is recommended as a replacement.
