Vinyl Cover - BTI OSL Signs
For those of you that requested a cover to protect your sign and for the others that requested a means to have a solid background
for that state that doesn't allow light to shine through your sign, BTI has come up with a vinyl cover with the
"OVERSIZE LOAD" lettering on both side. It slips over your sign from the top and attaches with
Velcro on the bottom. It will not save you fuel if you run with the
sign in its upright position, (and we all know what that is costing us these days)
but it will prevent light from shining through. You can always remove it when you reach a state that allows you to conserve fuel, help
protect the environment, and doesn't mandate that you drive with a sail on the top of your vehicle.
Cover is Safety Yellow Vinyl with Black Lettering and weighs 5.0 pounds.
