A plasterboard hole liner for ceiling down lights, maintains the strength and integrity of material into which the hole is formed, preventing damage to soft gypsum plasterboard ceilings. The hole liner may be made of metal and comprise a flange. It can be fixed either with tabs which fold out over and grip the plasterboard, or pins. The hole liner maintains pressure against the retaining springs of the downlight, for repetitive insertion and removal for decorating and for maintenance. |
