Equipped with a 70 kg selectorized weight stack and certified to CE standards, the F87B is the ideal leg-training station for commercial gyms, strength zones and bodybuilding facilities.

Product Description

The F87B Seated Leg Extension/Leg Curl Machine is a pin-loaded (selectorized) strength training unit purpose-built for dual-function lower-body development. Its ergonomic motion track delivers smooth, guided resistance through the full range of both knee-extension and knee-flexion movements, effectively isolating the quadriceps during leg extensions and the hamstrings during leg curls while maintaining stable joint alignment. The heavy-duty steel frame with 3 mm wall thickness ensures exceptional structural rigidity and long-term reliability under continuous commercial use. The 70 kg selectorized weight stack provides a wide range of precise resistance adjustments, allowing users to progress safely from light activation sets to heavy strength work. High-density foam padding, upholstered in abrasion-resistant, water-repellent leather, offers comfortable and secure body positioning. Fully customizable frame colors, upholstery and logo branding are available, with CE certification and wooden case packaging for international distribution.
