Built for property managers and building owners who need reliable access control, quiet operation, and smooth traffic flow in high-cycle parking environments. Our operators are engineered to be fast while staying exceptionally gentle on the door, helping reduce wear and extend door life.
Parkades run on repeat cycles, tight clearances, and tenant expectations. When a door stutters, stalls, or fails, it creates congestion, security risk, and costly service calls. GDI operators are engineered to deliver consistent movement, quiet performance, and integration with modern access control systems, while providing fast cycle times with gentle acceleration and deceleration that helps your door last longer.
Many underground garages use low headroom track (double top tracks) where overhead space is limited. The GDI-JDMG trolley is ideal for these conditions, providing smooth door control while staying compatible with tight ceiling layouts.
