Yes, back in 2010 we added 2 new adaptors, the CP10-242 which is a 1 ¼” conduit adaptor and the CP10-243 which is a 1 ½” conduit adaptor. These are only available as accessories that would have to be purchased in addition to a CP10K. We will not switch out any of the adaptors that are normally included with the puller in exchange for these. The CP10K includes the 2” – 4” conduit adaptors. We currently do not offer any adaptor for conduit sizes larger than 4”.
