We’ve even had customers try to use siding nails (for Hardie) in this nailer - the heads of those nails are too small and they won’t fire in this nailer. Use 1 3/4” coil roofing nails only and you’ll get sure fire consistency 👍 Our adapters and hooks are available at sidingtips.ca only and we ship worldwide. . . . . . . . . . . . . . . #vinylsiding #sidingtips #dewaltsidingadapter #cordlessvinylsidingnailer
