Seal FLE 220 / 380
Pull-tight seal, the highest level of protection, new improved collet design.
Transparent cap allows to control integrity of the collet when locked.
Double numbering, on the collet and on the bracket.
Two holes on the bracket allow to create two buckles to fix a label for example, and to reduce the lenth of the remaining stalk.
Other colors on request - but it should be light to read the bar-code clearly.
