In the NT-0105 model, the tool has a tri-hole design and features three holes (i.e., 3 holes) with precisely selected diameters. Each hole is responsible for a different stage of preparation in order to remove successive layers as securely and evenly as possible:

• Removing PVC coating/sheath 2-3mm – for working on cables with a diameter of 2-3mm (up to 3mm) and initial preparation of the section when it is necessary to cut and expose further layers.
• Buffer removal (900µm) – hole for removing the buffer, i.e., the 900µm buffer (900 µm / 900) in tight-buffer cables and many patch cords.
• Varnish removal (250µm) – a hole for removing the protective layer from fibers with a diameter of 250µm, down to the 125µm glass level.

Precision is key: the stripper must guide the blade so that it removes the layers “cleanly,” without damaging the core or scratching the glass, which is particularly important before splicing and when working on short sections of optical fibers. This 3-hole arrangement is known, among others, from the popular CFS-3 (tri-hole) design used for stripping 2–3 mm, 900 µm, and 250 µm.

In field work, it is not only the diameter and coating that matter, but also ergonomics. The NT-0105 is a convenient tool for quick cable handling and fiber preparation in both building installations and loose tube cables (after opening), when it is necessary to precisely remove successive layers.

Key benefits:

• Lightweight design – less hand fatigue during serial fiber preparation.
• Ergonomic shape and comfortable grip – secure grip even when wearing gloves.
• Blade lock – protects the stripper from accidental opening during transport and in the toolbox.
