Lamello® Hex key SW 4 mm, extra-long (120 x 50 mm) (Item No. 271945A)

Lamello® hexagonal pin spanner, size 4 mm, extra-long (120 x 50 mm) – special tool for deep access holes

The original Lamello® hexagonal pin spanner, size SW 4 mm, in an extra-long version (item no. 271945A) measuring 120 x 50 mm is the perfect specialised tool for conveniently tightening and loosening Lamello Clamex connecting fittings (such as Clamex P-14, Clamex P-10 and Clamex S-18) in deep cabinet constructions and hard-to-reach installation situations.

Thanks to the extended arm length of 120 mm, even deep-set Ø 6 mm access holes in thicker side panels or in large-scale furniture can be reached without any difficulty. The precision-manufactured SW 4 spanner size engages positively with the lever mechanism and enables reliable torque transmission.

Applications and mode of operation

The extended hex key offers decisive advantages in demanding furniture constructions:
