The 250-03 R1-Radius Rail Clamp resolves a long standing issue! It joins R1- or R2-radius curved track smoothly and strongly--without strain and with excellent conductivity. Your choice to use either 250-03 radius clamps or 250-07 adapter clamps for R3-radius curves; R4 and larger radius curves are so gentle that they may be joined by either 250-07 adapter clamps or 250-01 straight clamps.
250-03 clamps completely around the rail flange--top, bottom and edges--as well as the base of the rail web. This exclusive Hillman design results in a joint that is extremely strong in all 3 dimensions and that ensures conductivity.
