0.125" - $1.35 (pn 162288ch)
0.250" - $1.35 (pn 162270ch)

Funny you should mention this today of all days. I am scheduled to receive a shipment today from Jameco today with 5 different sets of these exact Spider Couplers and spiders. There are actually a couple additional sizes available on-line that aren't mentioned here, but the application is identical.
Ahhh, the saying is true, "Great minds think alike"
BTW, adding a small zip tye to the heat shrink on a round shaft makes the bond more secure!
