        Purlmate 3650 | Top Hat purlin mounting block for GPOs and switches | White PVC, Australian made

        The Purlmate 3650 is a fully enclosed plastic mounting block that fits standard power points, socket outlets and light switches directly onto 64mm Top Hat steel purlins. The block clips into the purlin frame, accepts 25mm conduit at each end, and keeps the wiring enclosed behind the faceplate. The Purlmate 3650 is Australian manufactured and independently tested by a NATA accredited laboratory.

        The Purlmate 3650 is the block most sparkies specify when wiring out a shed, workshop, or steel-framed garage. On Top Hat purlins there is nothing flat to fix a power point or switch to, so the block provides the mounting platform for the accessory. It removes the need to fabricate a timber or homemade backing block on every outlet position. The moulded 25mm conduit entries let the conduit run straight in and sit neatly. Because it accepts standard power points and switches, the same plates installed elsewhere on the job fit straight onto it.

        For sparkies fitting off a shed or new workshop, the Purlmate 3650 turns an awkward installation into a straightforward one. Clip the block to the purlin, run the 25mm conduit in, and secure the faceplate directly. Units can be gang-joined where a bank of outlets is needed above a workbench, and the fully enclosed body keeps the wiring contained and protected. The Purlmate 3650 is Australian made and designed, with the housing tested by a NATA accredited laboratory.

        Where to use the Purlmate 3650

        • Steel-framed sheds and garages — where outlets land on Top Hat purlins
        • Workshops and home workshops — banks of GPOs above a workbench
        • Kit homes and modern steel-frame builds — power points and switches on purlin walls
        • Carports and patios with steel framing — surface points without a flat backing
        • Farm sheds and rural outbuildings — quick fit-off on shed framing
        • Re-wires and additions in existing sheds — adding points without making a backing block

        The Purlmate 3650 is designed to clip into 64mm Top Hat purlins. Check the purlin profile on the frame before ordering, as deeper or non-standard sections may not seat the block correctly.

        Verified Sparky Direct customer reviews: Purlmate 3650 Mounting Block (3650)

        "Made fit out in my shed super easy, massive time saver" — Shane

        "These fit perfectly well made and strong" — Matt

        "These look very professional." — Andrew

        (PURLMATE3650)

        The Purlmate 3650 is shaped to clip into 64mm Top Hat steel purlins, the framing used in most sheds, workshops and steel-frame builds. It fits virtually all standard 64mm Top Hat sections. Check the purlin profile on your frame before ordering, as deeper or non-standard sections may not seat the block correctly.

        Standard power points, socket outlets and light switches mount to the Purlmate 3650, so the same plates used elsewhere on the job fit straight on. The block provides the flat fixing base and the conduit entries; the GPO or switch is supplied separately.

        The Purlmate 3650 is a mounting base only, but connecting a power point or switch to mains wiring is electrical work that must be carried out by a licensed electrician. The block itself clips to the purlin and provides the conduit entries and fixing points.

        The block has a fully enclosed body that keeps the wiring contained and protected behind the plate, and the housing is tested by a NATA accredited laboratory for electrical safety. Moulded 25mm conduit entries at each end let the conduit run straight in.

        Blocks can be gang-joined to create a bank of outlets, which suits a row of power points above a workbench. Each block has two 25mm conduit entries plus a 20mm knockout on the back for rear entry, so conduit can run between joined units.

        The Purlmate 3650 carries a 1-year warranty for both domestic and commercial use, starting from the invoice date and handled as a return to Sparky Direct. The block is Australian made and designed.

        Great Special Purpose Mounting Block on 17 April 2018

        If you are installing standard size plates (power points, light switches, etc.) in a shed with Top Hat rails, these are magic. One note of caution though. Be careful driving those screws that attach the switch plate. They have to tap a fairly long thread into plastic and I have had problem removing these screws later. I think it was caused by using a powered screwdriver with excessive speed, possibly embedding the screw at high temperature. Removal is by destruction. :-(
