AC&M’s Model PSW-97® stands out as a superior option for sealing with wire. This unique plastic and wire security seal locks without tools and can be used with various wire types or specialty cords of any length to fit almost any seal application.

Wire seals are the oldest and most versatile type of tamper-evident seals. Wire seals with lead, commonly used in the past, are being replaced for most wire seal applications. This has introduced a range of alternatives.

The PSW-97® locking mechanism is a security innovation originally patented by AC&M. Its stainless steel plunger (key) pushes and snaps firmly into place inside the seal, and effectively deters or exposes tampering. Unlike other plastic & wire security seals, wire options are almost unlimited, because the wire is not attached permanently to the seal body, leaving you with the ability to choose the right wire type and length every time.

The tamper evident seal is applied by inserting twisted wire of various metals (3-ply or 4-ply galvanized steel, stainless steel, or copper are available). Because the wire is not permanently attached we can supply it in convenient pre-cut lengths, or on bulk rolls for compact storage and cut to any length by users.

The body shape allows larger marking and high readability compared with other wire seals. Large letters and sequential numbers can be stamped into each seal for clear visibility over an extended time in use. They also can be custom stamped with a logo, or various languages and symbols. Beyond custom marking we also can provide customized, packing, wire options, delivery scheduling and more.

PSW-97® is easily locked without tools. The locked seal has nearly 45 kgs (100 lbs) of breaking strength. Though strong and resistant to accidental breakage, the security seals are removed with common wire cutting tools, and cannot be re-used.

Common applications include utility meters and other metering devices, storage boxes, cabinets and bins, lockouts, coin boxes and other types of locks and closures with openings of 1mm or more.

The PSW-97® has been tested and proven to remain secure during continuous outdoor use in harsh climates. Standard PSW-97® bodies are made of premium styrene plastic in opaque or transparent colors, as well as clear. For severe-duty choose our optional solvent-resistant acetal polymer. Both materials are durable while providing excellent visible evidence of attempts to open by force, or tampering with the seal. The body shows fine cracks or fracture marks when this occurs.
