Gutter Crimpers, Outlet Punches & Rivet Guns

Once a gutter run comes off the trailer-mounted seamless gutter machine, it still has to be finished by hand. Crimpers, outlet punches, and rivet guns are the tools that turn a straight length of formed metal into a working system — cutting clean outlet holes, folding tight miters at corners, and setting rivets that hold end caps and joints closed against wind and water.

Where These Tools Come In

Outlet Punches — Cut a precise opening for each downspout connection so water drops straight into the leader instead of overflowing at a rough-cut edge.
Gutter Crimpers — Fold and lock corner miters and end caps by hand, matching the profile produced by the on-site forming and roll-forming equipment.
Rivet Guns — Set the fasteners that hold end caps, straps, and miter joints together, sealed to stay tight through repeated heat cycling.

Why It's Done On Site

Fabricating and finishing gutter to length in your driveway means every outlet, miter, and cap is fitted to the actual run on your house, not to a stock length cut somewhere else and forced to fit.
