Compatibility / Fitment Guide
Direct fit criteria: round oar shaft measuring 43–44 mm at the intended collar position and a rowlock whose opening/shape accepts the collar profile. Measure the bare shaft with calipers; varnish, wraps, sleeves or taper can change the effective diameter.
Size cross-check: Osculati lists 34.565.01 for 34/35 mm, 34.565.02 for 38/39 mm, 34.565.03 for 43/44 mm, and 34.565.04 for 53/54 mm. Choose by measured shaft diameter, not boat type or oar length.
Installation note: this rigid collar must be installed using the manufacturer’s opening/retention method; do not assume it simply slides over an oar blade or oversized grip.
