This Stonfo Magnifying glass is specially designed for tying vises, which allows you to see clearly and without distortion small details during the tying phases of the fly, without using your hands.
It is equipped with a flexible arm that can be adjusted in any position with a small attachment at the end that allows a secure and stable locking on the vises stem from Ø 8 to 10 mm (3/8″) and on accessories stems Ø 5 mm.
A suction cup model is also available, with a lever device to ensure rapid and safe locking.
By removing the suction cup, this lens fits perfectly into the integrated tool holder of the TRR base (art. 657), the base of the ELITE vise (art. 653) and the base of the TRANSFORMER vise (art. 654).
