Product Advantages

1. As a result of its deep post insulator, Nabla Rail Clip offers exceptional resistance to wear caused by lateral loads. This reduces track maintenance overheads.

2. Nabla Rail Clip is simple to install, saving time and money.

3. The use of glass-reinforced material results in a high level of mechanical strength and good lateral force absorption.

4. Nabla Rail Clip offers higher electrical insulation than similar systems, making it an efficient, effective option.

5. The system has been adapted for compatibility with all types of rail, including grooved, AREMA and industrial. The system offers a good level of lateral adjustment via the insulators, allowing fine gauge tuning and alignment.

6. By maintaining the track gauge on tight radius curves, Nabla Rail Clip increases the life expectancy of assembly components.
