outer end 50 of the insert member 10 so that electrical cable 95 that is fed up over the sloping surface 120 immediately enters the channel 30 for ultimate entry into the pipe 60 this sloping surface replaces the need for a roller at such outer end 50 of the insert member 10 as can be seen from the drawings formed on opposing sides of the outer end 50 adjacent to the sloping surface 120 of the insert member 10 are opposing flanking support members 130 a and 130 b that are substantially rectangular plate members affixed on their inner surface to the outer surface areas of the insert member 10 as seen more specifically in the preferred embodiment of the subject invention the sloping surface 120 is flanked by integrally attached flanking support members 130 a and 130 b which help center the insert member and maintain the wire centered and confined as it passes over the sloping surface 120 as can be seen from the drawings the insert member 10 is partially inserted into the open end of pipe 60 by placing the inner end 40 thereto into the pipe cavity with the upper channel 30 facing towards the center interior of the pipe 60 with the lower surface 70 of the insert member 10 resting conformingly against the interior cavity 100 of the pipe 60 once the insert end 40 of the insert member 10 is placed in the inner cavity.
