Locking format
Adjustable pull-tight; beaded tail
PRODUCT OVERVIEW
A clear specification for your application.
The MC-250B is an adjustable, single-use plastic seal with a beaded tail and a compact locking head. Its pull-tight mechanism allows the loop to be adjusted around a compatible closure. The catalogue specifies 100% new PP and an all-plastic construction, with an approximate piece weight of 1.8 g. Use the total length, closure opening and required loop size to check the fit. The 250 mm measurement is overall length; a usable working length is not stated in the catalogue. Artwork, color choice and quantity should be reviewed together before order confirmation.

DIMENSION REFERENCE
Check the fit before ordering.
Drawing: 250 mm overall length, flag 40 × 20 mm, bead diameter 2.6 mm. Working length is not specified.
APPLICATION CHECK
Match the seal to the closure.
Four distinct example applications: a delivery vehicle door latch, an express parcel transfer tote, a garment label and hang tag, and a bank document handover bag. Match each closure opening, required loop and identification procedure to the model. MC-250B is a light-duty all-plastic seal. A vehicle illustration shows an opening check on a compatible latch, not a tested high-security cargo classification. Confirm fit and handling with a sample; choose a documented model when transport requirements specify a tested classification.
Thread through the aligned holes of the closed latch and fixed hasp, then lock and record the identifier. Confirm fit and use a documented cargo seal when a tested classification is required.
