The Cambridge Security Seals Heavy Duty Pull Tight Seal is an adjustable plastic tamper-evident seal available in four lengths, 9", 12", 15", and 18".

The seal's proprietary technology and engineering allow it to have a unique and thinner diameter that is actually 40% stronger (as measured by tensile strength) than similar industry alternatives. The combination of increased strength and a thinner diameter is a critical benefit when securing items that require the seals to fit through small apertures.

As an added feature that both reduces cost and is environmentally friendly, Cambridge Security Seals' unique Clean Break Design® ensures that individual seals detach from the strip without any plastic waste. Cambridge Security Seals offers its Heavy Duty Pull Tight Seal in seven colors and provides customers with the unsurpassed ability to customize their seals with logos, printed information, variable numbering, and barcodes. Online orders are 12" in Red or Blue. Call to order other colors and sizes. Made in the USA.
