Pin Type Carriages
The "Pin-Type Carriage" is a less common type of carriage. All your attachments hang from a round rod or pin. It will be necessary to learn the pin's size or measurement.

 

We will also need to ask questions surrounding different aspects of the carriage such as bracing and clearances of of your carriage.

NOTE:
When ordering for a Class IV carriage, we will also need to know the thickness of your carriage and whether it is tapered or square.

Also check the bottom carriage bar to determine if it is square or tapered.
