DURABLE ALUMINUM: 'Do Not Knock' signs are made from heavy-duty 40 mil thick aluminum. Unlike steel signs, our aluminum signs do not rust. Signs easily last up to 7 years outside.
EASY INSTALLATION: Signs have four 3/16 inch corner holes. Mount with screws, nails, tie-wraps or wires. Signs can also be attached with foam or double-sided velcro tape. Sign attachment accessories are not included.
LAMINATED PROTECTION: With lamination, graphics are protected from weather and abuse to preserve a fresh look. Graffiti can be cleaned off too. Clear UV laminate resists chemicals, UV rays, water, and abrasion.
MADE IN USA: All components are made in the USA and offer superior quality.
PACK CONTENTS: One 10 x 7 inch red and white aluminum sign.
