Description
The Left Shoulder Closed sign with blank distance area allows the installing agency to add a custom distance or leave blank. Used in temporary traffic control applications under MUTCD Part 6 where a standard distance legend does not match the site conditions.
This listing is for the blank distance version of the W21-5bL sign. The distance area is left open for field application or general use without a specific distance. Choose the sign size based on roadway type and required visibility. Four sizes fit this blank sign: 24" x 24", 30" x 30", 36" x 36", and 48" x 48". The 24" x 24" is intended for edge work on private property, like a business park road. Manufactured on .080" rustproof aluminum with rounded corners and pre-punched mounting holes. Other distance variants are available as separate listings. Hardware sold separately. 48" signs ship truck freight.
