Many framing nailers offer sequential (single-shot) and contact (bump) firing modes. Some models have a selectable or dual-mode switch that lets you change between sequential and bump/contact operation.
Coil framing/siding nailers typically hold hundreds of nails (examples show capacities from about 225 up to 300). Strip/round-head framing magazines commonly hold around 60 nails.
Many models offer tool-free depth adjustment—typically a hand-operated depth wheel—that lets you quickly change driving depth for different materials without tools.
These nailers are air-powered (compressed air). Product details explicitly indicate they do not use a battery.
Nail length ranges vary by model. Coil framing/siding nailers commonly accept about 1-3/4" up to 3-1/2"; other models list ranges such as 2"–3-1/4" or 1-3/4"–2-3/4". Overall, the combined span is roughly 1-3/4"–3-1/2".
Features that help clear jams and keep work moving include open-nose or quick-release noses for fast jam removal, anti-dry-fire mechanisms to prevent blank firing, dust caps or exhaust control to keep the tool cleaner, and selectable firing modes (sequential or bump) that can reduce misfires and interruptions.
