(Anchor Bracket)

Field installations have several optional methods of anchoring the FLEXSTEP system at the top to prevent any vertical movement of the system.

Most basic anchoring systems use the standard Anchor Bracket. This bracket is bolted to the first series of belt holes and provides four holes thru which anchor pins can be driven (if the lining allows) or thru which cabling can be connected to attach a “dead-man” anchor system beyond liner.
