When selecting a pneumatic coil framing nailer, buyers should confirm compatible nail collation angle, nail length, shank diameter, head diameter, shank type, operating pressure, body weight, magazine capacity, depth adjustment, and application environment. For CN90B, the compatible fasteners are 15 degree flat wire coil nails from 50mm to 90mm with 2.87mm-3.3mm shank diameter.
For high-volume construction or pallet production, a high-capacity coil magazine and comfortable grip can improve fastening efficiency. For long working shifts, the magnesium body version can help reduce handling fatigue.
