Abstract

A temporary railing for a boundary of a building floor may include a plurality of temporary cable supports spaced along the boundary of the building floor, a plurality of vertically spaced apart cables carried by the temporary cable supports, and an access opening assembly for permitting temporary establishment of an access opening through each of the cables. The access opening assembly may include a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position, and at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when the cable jack is in the released position.

       12 . The temporary railing according to  claim 1  wherein the building comprises at least one vertical building member; and wherein said plurality of temporary cable supports comprises at least one pulley temporarily secured to the at least one vertical building member.  
   
   
       13 . A temporary railing for a boundary of a building floor comprising: 
 a plurality of temporary cable supports spaced along the boundary of the building floor;    a plurality of vertically spaced apart cables carried by said temporary cable supports to extend along the boundary of the building floor;    an access opening assembly for permitting temporary establishment of an access opening through each of said cables and comprising 
 a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position,  
 at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when said cable jack is in the released position,  
 an openable link selectively coupled in line with the respective cable adjacent said cable jack, and  
 a cable jack lock to lock said cable jack in the closed position.  
   
   
   
       14 . The temporary railing according to  claim 13  wherein said openable link comprises a hook and an eye to receive said hook therein.  
   
   
       15 . The temporary railing according to  claim 13  wherein said cable jack comprises first and second end members, a pivot member between said first and second end members, and a handle member coupled to said pivot member.  
   
   
       16 . The temporary railing according to  claim 13  wherein said at least one cable clamp comprises: 
 a primary cable clamp; and    a back-up cable clamp to be coupled to the respective cable adjacent said primary cable clamp.    
   
   
       17 . The temporary railing according to  claim 16  wherein said at least one clamp further comprises a tether coupling said primary cable clamp and said back-up cable clamp together.  
   
   
       18 . The temporary railing according to  claim 16  wherein said primary cable clamp comprises: 
 a pair of adjustable cable gripping jaws; and    a pair of handles extending outwardly from said cable gripping jaws.    
   
   
       19 . A temporary railing for a boundary of a building floor comprising: 
 a plurality of temporary cable supports spaced along the boundary of the building floor;    a plurality of vertically spaced apart cables carried by said temporary cable supports to extend along the boundary of the building floor;    an access opening assembly for permitting temporary establishment of an access opening through each of said cables and comprising
