Adjustable from 0.5" to 4" this is keyspanner is for small diameter optics, sturdily built for a lifetime of service. The rigidity of the keys permits use in tight quarters without springiness. The keys, once engaged in the correct positions of mounting flanges, gives one a positive and most rigid action avoiding slipping and damage to optics. An indispensable tool for scientific instrument makers, engineers, repair shops, and all users of optical tools. Includes 3 sets of keys (1 set round tips 1.5 mm and 2 sets rectangular tips, 1.0 mm and 0.45 mm.)

Consists of two coil springs with their turns interleaved, attached to two arms projecting from and sliding for adjustment of diameter on the main supporting bar. Coil springs, each one adjustable for a range of diameters, can be quickly interchanged giving an infinite variety within the capacity of the tool. A spring of approximately the same diameter is placed over the work to be turned, and the coils of the spring tighten as the main bar is turned, thus effecting a tenacious, equally distributed friction grip which renders the assembly or dismantling of the most fragile threaded cell or thin wall tube the simplest operation, without risk of damage or marking. Right or left-hand threads can be dealt with by turning the springs 180° on ...
