Why Choose the WAGO 249-116 Screwless End Stop?
The WAGO 249-116 is a compact and reliable screwless DIN-rail end stop designed to secure rail-mounted terminal blocks and other compatible components against unwanted movement. Developed for 35 mm DIN rails, its tool-free snap-on design enables fast installation without conventional fixing screws.
The 249-116 uses integrated clamping plates to provide a secure hold on the DIN rail, helping keep terminal block assemblies firmly positioned even where the rail is installed vertically. Its screwless construction simplifies panel assembly and can reduce installation time when large numbers of terminal blocks and accessories are being fitted.
With a width of just 6 mm, the WAGO 249-116 occupies minimal DIN-rail space and is suitable for both 35 × 7.5 mm and 35 × 15 mm DIN rails. The grey polyamide housing incorporates marking facilities for clear identification within electrical control panels, distribution systems and industrial automation installations.

Reliable DIN-Rail Terminal Block Security
End stops are used to prevent terminal blocks and other rail-mounted devices from shifting along a DIN rail. The WAGO 249-116 achieves this without a conventional screw mechanism, allowing installers to simply snap the end stop onto the rail while its integrated clamping system maintains a secure position.
Its compatibility with standard DIN-35 rails makes the 249-116 suitable for a broad range of electrical control and automation installations. The compact design is particularly beneficial in densely populated control cabinets, while the integrated marking options help installers organise and identify terminal block groups clearly.
Typical Applications
- Securing terminal block assemblies on DIN rails.
- Industrial electrical control panels and cabinets.
- Machine building and factory automation systems.
- Power distribution and control equipment.
- PLC and industrial I/O installations.
