Product description Durable aluminum alloy frame with dual sliding anchor plates Solid construction resists bending and wear during repeated use. Dual sliding anchor plates allow precise foreandaft positioning for consistent foot placement and secure anchoring to the track. Secure, nonslip pedals for reliable starts Thick nonslip rubber pedals provide strong grip and longlasting performance on both plastic and cinder surfaces. Elastic pedal locks and screwchannel locking ensure the pedals stay set during powerful sprint starts. Six preset angle adjustments (15°–65°) via screw channels Quickly set the pedal angle across six presets to match athlete preference and height. Screwchannel locking provides a secure, vibrationresistant hold once the angle is set. Designed for both cinder and plastic tracks Builtin spikes for firm anchoring on cinder tracks. Reinforced rubber pads protect and grip plastic/synthetic runways without damage. Swap between surfaces without additional tools or accessories. Easy transport and precise setup Integrated carrying handle makes it simple to move between training and competition. Internal guide rail scales let coaches and athletes reproduce exact pedal positions for consistent starts. Compact adjustments and quick locks reduce setup time at meets and practice. Why you need it Delivers stable, repeatable starts by combining rigid construction, secure locking, and tailored angle settings. Works reliably on both cinder and plastic tracks, removing the need for separate equipment per surface. Saves time for coaches and athletes with simple, measurable setup and an easy carry solution.
