249-101 Wago Screwless end stop;6 mm wide;for WMB markers;gray

Why Choose the WAGO 249-101 Screwless End Stop?

The WAGO 249-101 is a compact screwless end stop designed to secure terminal blocks and associated components in position on a 15 mm DIN rail. With a width of just 6 mm, it provides dependable mechanical retention while helping maintain a neat and space-efficient terminal assembly.

Designed as part of WAGO's terminal block accessory range, the 249-101 uses a screwless locking design that simplifies installation and avoids the need for conventional screw fastening. It is also designed for identification with WMB markers, allowing clear and consistent labelling within control panels and electrical equipment.

Manufactured from durable PA66 polyamide with a UL 94 V-0 flammability classification, the grey WAGO 249-101 is suitable for demanding industrial electrical environments. Its compact dimensions and low weight make it particularly useful for miniature DIN-rail assemblies where installation space is limited.

Reliable Terminal Block Retention for Compact DIN-Rail Assemblies

End stops are used to prevent terminal blocks and other rail-mounted components from shifting along the DIN rail during installation, wiring and operation. By providing positive mechanical retention at the end of a terminal strip, they help maintain an orderly and secure electrical assembly.

The WAGO 249-101 combines this function with a compact screwless design suited to 15 mm DIN rails. Its compatibility with WMB markers also provides a convenient identification point, making the accessory useful in compact control equipment, machinery and distribution assemblies where both secure mounting and clear labelling are required.

Typical Applications

• Compact terminal block assemblies.
• Industrial control panels.
• Machine-building electrical systems.
• Automation and instrumentation equipment.
• Junction and distribution boxes.
• 15 mm DIN-rail installations.
• Electrical equipment requiring secure terminal retention.
• Assemblies using WAGO WMB marking systems.
