Help please with propane extension 2108DS

[gkooris]

Hi,

We just took delivery on a 2108DS trailer. There's a propane feed for a BBQ with some kind of snap fitting on it. Can someone tell me what I need to attach an extension that will go from that snap fitting to the regulator on my grill, or directly to the grill, since there's already a regulator on the trailer?

Thanks in advance!
