Retta RCA1213 Two-sided Trichotka Key is a practical and multifunctional tool designed to work with fastening elements in 12 × 13 mm. This model is widely used in both technical services and various mounting works, as it is equipped with 12 mm, and 13 mm-size headlines on the other hand. Thanks to the Trichotka mechanism, it is possible to quickly and continuously squeeze the connectors without turning back, which accelerates the work process and reduces the physical burden. The key is highly resistant to corrosion because it is produced by chrome-vanadium steel and does not change its form during long-term use. The erasive ergonomic handle that does not slip the hand allows you to easily manage and does not create such fatigue in use for a long time. Retta RCA1213 is a valid tool for both professional masters and household users in the tool set.
