4648A Bolt Pattern

[John Y.]

Anyone know what HF mounts are compatible with the bolt pattern on the top of the 4648A?

Check the 2509A in the Tent Sale.

10 Watt Street,

I had suspected that would fit. But that only accounts for two bolt holes. There are also two along the centerline. Wonder what those are for? Thanks.

BTW, anyone know the exact height of the 2509A from the bottom up to the bolt where the unit pivots in the vertical direction?
