Avoid structural damage by clearly displaying the maximum canopy height in your drive thru lanes. We have created a number of different Clearance Signs to display warnings on low canopies. Whether it be Clearance Signs with the maximum height allowed or a sign to create a special lane for “TRUCKS/VANS, we can help you inform motorists. These clearance signs are available in direct-view LED, backlit LED illumination, long-life neon illumination, and incandescent-illuminated signs. Non-illuminated signs are available as well.
