A barbed tape product as adjacent pairs of loops in which the loops of a
pair are attached to each other at an attachment point that is
circumferentially offset relative to an attachment point of the adjacent
pair of loops. Additional attachment points may be provided in helically
progressive positions between the first and second attachment points. The
attachment points are positioned on one pair of loops so that each of the
attachment points are circumferentially offset relative to all other
attachment points on an adjacent pair of loops. The attachment points may
be positioned in a predetermined helically progressive pattern on a coil
of the product. The pattern may provide a predetermined natural
configuration of the product when the product is in a deployed state of
use. Attachment elements for attaching strands of the product together
are sized and configured for strength and accuracy in automatically
attached concertina or other barbed tape products.
