The ProtectR features a solid, lightweight 1.5mm steel security cable,
which provides a perimeter barrier around the BlackRapid camera strap or
any 1.5" wide bag strap. Ideal for travelers who want some added
security for their straps in unfamiliar surroundings. By design, there's
an added a level of deterrent by exposing the cable through small
cut-aways in fabric to reveal the cable.
