OBO MS41SN M8 ZL Sliding Nut for MS4121/MS4141 Profile Rails, M8 Thread, Electro-Galvanised Steel

Electricians and panel builders working with OBO MS4121 or MS4141 profile rails rely on this sliding nut to secure cable trays, clamps, and mounting brackets without drilling or welding. The M8 thread accepts standard bolts, while the short spring holds the nut in place during assembly, allowing one-handed positioning along the 41 mm rail channel.

Key specifications

• Thread size: M8
• Material: steel, electro-galvanised for corrosion resistance
• Compatible rails: OBO MS4121 and MS4141 profile rails (41 mm width)
• Spring mechanism: short spring for secure sliding and positioning
• Installation: slide-in from rail end or snap-in at any point
• Product type: sliding nut / channel nut

Why choose it

The electro-galvanised coating protects against rust in indoor and sheltered outdoor environments, extending the life of your mounting system. The short spring design ensures the nut stays in place even when the rail is vertical or overhead, reducing installation time and frustration. Its compact profile fits neatly within the rail channel, allowing multiple nuts to be positioned close together for dense cable runs.

Ideal use cases

• Mounting cable trays and trunking on OBO MS4121/MS4141 rails
• Securing pipe clamps, junction boxes, and sensors in control cabinets
• Creating adjustable fixing points for future modifications
• Overhead or vertical installations where nuts must not slide freely

Good to know

Each nut is individually packaged and ready for immediate use. For best results, pair with OBO M8 bolts and washers. The sliding nut is part of the OBO MS41SN series, known for reliable performance in electrical and mechanical installations.
