THE Fortway three-slam van-door Jock is a very neat fitment which should appeal to coaehbuilders handling bodywork for industrial motors. Amon,* the advantages of the design are that the door, or pair of -doors, is secured at three points, namely, the top, bottom and centre, by means of slam
locks of the conventional type. All three are coupled together and operated by a single key and handle. To undo the locks a T-handle is inserted in the ordinary way, given a partial turn and the door can be opened.
Similarly, when closing the door, if it be pushed to, the slam locks will operate without the need for using the handle. The door is then held securely, but, of course, it can be opened by anybody with a normal type of T-handle. To give security, one key is inserted in the central three-lever lock, and when this has been used all three locks are fastened and can only be undone by the possessor of a suitable key.
It will be seen that although the door
is held at three points, only one of them needs operation, so that time is saved, because the door can be shut without having any bolts to attend to and there is not the fear—which exists in manycases—that the lock has been closed, whilst the top and bottom bolts have been forgotten. In the latter eircum stances, of course, the locking of the door is of very little value. This 'Joint is obviated by the Fortway design.
A set includes the three slam hicks two flexible rods which can adapt themselves to any contour of door, fixing staples and two keys. Two sizes are available—namely,
those having a central lock of 6 ins. by 2-1 ins., or 4 ins. by 2 ins.
In the matter of fitting, all that has to be done is to screw on the three locks after cutting the flexible coupling rods to the correct length and riveting them to the projecting . arms of the central or main lock. Very little woodwork has to be cut away to accommodate the locks ; this, of course, saves time and money.
Another point is that no independent lock has to be fitted, as is often the ease when the door is normally held closed by bolts. The Fortway serves as bolts and locks. The prices, we hear,' are very competitive.
