One of the simplest--and most effective--security devices for your home is the classic door viewer. The ultimate in low-tech reliability without wires, batteries or buttons, it lets you visually identify visitors safely from behind a securely locked door. This premium-quality version is a 'big' improvement over standard-sized viewers because a larger diameter viewer--50% larger than standard--lets you see a larger, wider view of your front entrance. 1-1/2"-diameter brass case (1" diameter cylinder) with 3/4" glass view-lens, optical-quality 10-power magnification, precision-machined threads to allow accurate adjustment for door width. Includes optional black rubber gaskets for weather-proof fit. Easy to install in almost any door by drilling single one-inch hole at your desired height. Jack's Tool Shed Satisfaction Guarantee.
