A rectangular-to-round transition collar does not match the spiral size
Do not force the spiral or crush the collar. Verify nominal size, actual OD/ID, connection type, shop tag, and whether a reducer/coupling or remake is required.
Do not oval the spiral, beat the collar smaller, or seal over a connection that is not mechanically seated.
Check
Measure the collar outside diameter and the spiral/coupling size.
Check the shop tag and drawing callout.
Confirm if the connection needs a sleeve, reducer, coupling, or different fitting.
Support the pieces so alignment is not creating the mismatch.
Ask before crimping, cutting, or forcing.

Say this to your foreman
The transition collar at [location] measures [dimension] and the spiral/coupling is [dimension]. The drawing calls for [size]. Do you want a reducer/coupling, shop remake, or field adjustment?
