Review on Makita P-20177 Guide Rail Connector Kit, 2/pk: The Perfect Tool for Seamless Guide Rail Extensions by Brian Healy

TSO Products makes cranks so much better. Makita rods are just flat rods with no architecture whatsoever. The TSO bars are designed to fit into the top gap in the corner slot of the rails. This molding inserts the exact configuration of the bar into the socket that contains the mating piece, so the fit is perfect and can't wobble. In addition, the TSO set screw has a very wide face for excellent surface contact pressure compared to a basic Makita set screw with very limited surface contact.
