Gate corner insert

A method for removably attaching a gate rail to an upright, the method comprising:

• inserting the gate rail into a cavity defined by a plurality of walls of the upright through an opening in a first wall of the plurality of walls of the upright;
• inserting a gate corner insert into the cavity of the upright through a second opening of the upright defined by the plurality of walls, the gate corner insert including a base and a plurality of protrusions extending from the base, the base and the plurality of protrusions defining a second cavity therebetween, first and second protrusions of the plurality of protrusions defining a third opening therebetween in communication with the second cavity, wherein the base includes at least one hole extending therethrough, the at least one hole receiving a fastener therethrough, the fastener engaging against the gate rail when the gate rail is received within the third opening and the second cavity, the engagement of the fastener against the gate rail removably attaching the gate rail to the gate corner insert;
• positioning the gate corner insert within the cavity relative to the gate rail such that the gate rail is received within the second cavity and the third opening of the gate corner insert;
• and
• removably attaching the gate rail to the gate corner insert to inhibit removal of the gate rail from the cavity of the upright.
