VEVOR Coil Siding Nailer MCN55, 1 inch to 2-1/4 inch 15 Degree Pneumatic Siding Nail Gun, 70-120PSI Air Coil Nailer for Siding, Pallet Sheathing, Fencing, Decking

The product description doesn't mention anything about clearing jams. However, it states that the nailer reduces jamming and misfires. Customers consistently state that the nailer is easy to clear when jams do occur.

No, you cannot adjust the nail driving depth directly as there is no dedicated depth adjustment function. You can adjust the driving depth by changing the air pressure instead.

The recommended air pressure is 90-120 psi.

The product itself cannot adjust the depth, and the size of the air pressure needs to be adjusted to control it.

I did not find any information about compatibility with 16d nails in the product description or customer reviews.
