Type FL by Lindapter – The ONLY Fire Rated Beam Flange Clamp!

Lindapter Type FL Beam Flange Clamps are now independently Fire Rated for up to 120 minutes.

As part of our continued commitment and investment in product development and testing, Lindapter commissioned BRE Global Ltd (UKAS 0578) to independently fire test its Type FL Beam Flange Clamp.

Type FL is a fire rated connection solution for securing building services from structural or secondary beams without drilling or welding, including:

  • Fire Protection Systems
  • Sprinkler Systems
  • HVAC Equipment
  • Mechanical, Electrical & Piping
  • Acoustics Systems
  • Sanitation Fittings

Passionate about safety: For over 90 years, Lindapter has manufactured to the highest standards, earning a multitude of independent approvals and a reputation synonymous with safety and reliability. The Type FL is unique as it is the only beam flange clamp to be Fire Rated and also FM and VdS approved.

The products were tested in tension whilst subjected to a standard fire exposure in accordance with ISO 834 and ASTM E-119 for a duration of 120 minutes. BRE test report P123815-1002 Issue: 1 verifies load limits for 120 minute fire rating.

This testing provides contractors, specifiers and construction professionals with additional confidence and demonstrates our commitment to quality and transparency of product performance by increasing the volume of independent data we have.
