Get a QuoteAbout Locking Channel Gratings
The grating is fixed to its frame with stainless bolts, preventing scrap theft and displacement under traffic vibration — the safe choice for city centres and unsupervised routes.
Sizing follows flat gratings: match the channel width and pick B125–D400 by traffic. The lock does not reduce intake capacity.
