Description
The KATO 20-121 is a 4-pack of N Unitrack 1/3-length R315 curves at 15° arc — the fine-increment companion to the full-arc #20-120 (R315 45°, from batch 2), used for stepping out of double-track outer loops.
KATO N Unitrack system: Code 80 nickel-silver rail molded into a factory-attached ballasted plastic roadbed, with integrated UniJoiners. Unitrack is KATO's flagship N-scale track system established in the 1960s — the dominant N-scale sectional track worldwide.
