Has two mounting for spindles. There are three fixing legs attached to a bent arm reaching over the gutter.
This bracket is made from 1¼″ x ¼″ galvanised iron bar. The spindle mounting bar reaches out 8″ from the wall, its ends are rolled over to form a hole for the spindles. In the example here, the two spindles are 8″ apart, but other varieties have a 4″ spacing. Total length of the bracket is 18½″.
