Seen From Far Away: High Intensity Prismatic reflective film is 3x brighter than engineer-grade signs. Drivers catch these Do Not Enter signs early, so they stop in time. MUTCD R5-1 Size: 30x30 inch is the standard R5-1 size for single-lane conventional roads, so it reads as a real regulatory sign. Weathers Years Outdoors: Rust free aluminum with UV resistant ink makes these no entry signs weather resistant and fade resistant through sun, rain and freeze. For The Entrances You Are Responsible For: Private roads, driveways, one-way lanes, exit ramps, gates, loading docks and parking lots. Mounts In Minutes On Posts: Pre-drilled holes at standard spacing fit U-channel and round posts. WHEN A WRONG-WAY ENTRY IS YOUR PROBLEM TO SOLVE Most of the places that need a Do Not Enter sign never get one from the city. Private roads, apartment complexes, warehouse yards, exit ramps, one-way service lanes, campus drives and farm entrances are all yours to sign - and yours to answer for when someone drives in the wrong way. This is the sign for that job. WHAT YOU ARE BUYING - Do Not Enter sign, aluminum - High Intensity Prismatic reflective film, honeycomb pattern - Rust free aluminum, UV resistant ink, fade resistant - Built for permanent outdoor mounting WHY THE REFLECTIVE GRADE MATTERS Most listings in this category use engineer grade sheeting. This one uses High Intensity Prismatic, which returns roughly three times the light. At night, in rain, at the far end of an unlit lot, that difference is the entire reason the sign is there. SIZING 18 x 18 inch suits driveways, private lanes and low-speed interior roads. 24 x 24 inch is the usual choice for parking lots, apartment complexes and commercial property. 30 x 30 inch is the MUTCD R5-1 standard size for single-lane conventional roads, and is the right choice anywhere traffic approaches at speed or where the sign needs to read as fully regulatory. BUYING MORE THAN ONE Sites rarely need a single Do Not Enter sign. Most need one at each wrong-way approach. The multipacks cover a whole site in one order and work out lower per sign than buying singles. MOUNTING Mounts to standard U-channel and round sign posts, and bolts to fences, gates, bollards and building walls. Posts and hardware are not included. OLANZU
