Installation Information
For existing gutters installed using spikes, first remove the existing spike and ferrule. With a standard drill install the GutterScrew and ferrule using the #3 square drive bit provided. For new gutter installations, pre-drill a 1/4" hole with spacing as recommended by the gutter manufacturer, then install the new gutter screw and ferrule as instructed above.
Note: 7" FastenMasterGutter Screw is recommended for use with 5" standard residential gutter systems.
