Additional Specifications

Clearance Bar
Our hanging clearance bars will gives a visual notification with the bright yellow color and reflective copy. In addition to a visual stimulus, a physical impact to an overheight vehicle entering the structure will also be given. Not intended to damage a vehicle, the impact from the headache bar is enough to detour the motorist from entering and will in turn protect your parking garage or drive thru from physical damage.

Our hanging Clearance Bars come standard in a highly visible traffic yellow painted finish with black reflective vinyl. They are built with rugged extruded aluminum, making them designed for exterior use. If a custom clearance sign is what you are looking for, the length, color and message can be specific to your requirements.

Low Clearance Signs
Directional Systems has many low clearance signs that can be used both inside and outside of facilities, available in Direct View and Backlit LED. Our illuminated clearance signage options visually stand out in extremely bright to low-light situations.

Directional Systems even has a clearance sign that, coupled with sensors or loop detectors, can light up with OVERHEIGHT or STOP to warn motorists exceeding the clearance height.

If you don't see the low clearance sign you need, we can customize one to your specifications.
