3M DBI/SALA 8518001 Advanced Series 12-29" Adjustable Offset Upper Mast for use with Advanced Series lower masts, mast extensions and bases.  The variable offset upper masts are designed for use where multiple offset masts are required.  These masts are compatible with UCL Safety Systems Advanced lower masts, mast extensions and bases.  The 12"-29" variable offset upper mast may be equipped with front mounted and/or back mounted winches or self retracting lifelines and feature a 5,000 lb capacity anchor point for fall arrest anchorage.  For applications with overhead clearance restrictions, the adjustable height of the variable offset mast can eliminate the need for custom length masts and mast extensions.  The addition of the quick-release pin allows for easy collapsibility and transport."
