As it controls both Sash perfectly, bolting either or both securely in any position desired, thereby affording means for perfect ventilation, and at the same time absolute security against Burglars and Sneak Thieves.

It is easily operated, ornamental in appearance, and does not interfere with applying weather strips or inside blinds, and is the only Side Sash Mortise Lock that can be used in connection with inside screens, it having been constructed with special reference to the same. As a rule, Burglars and Sneak Thieves have little difficulty in entering dwellings through windows because of their insecure fastenings. Hence it is just as important that each and every window should be provided with a good substantial lock as that the front door should be.

Buy the Timby Burglar Proof, and take no other.
The Convenience and Absolute Security afforded will be ample reward.

Full Directions and Pattern for setting accompany each Lock Sold.
