Topaz Lighting 999 – Frequently Asked Questions

1) What mast sizes does the Topaz 999 adjustable SE wireholder fit?
The Topaz 999 wireholder adjusts to fit 1-1/4 inch through 3 inch, so one part covers the common service mast and service entrance cap diameters instead of stocking several fixed-size holders. If your mast falls anywhere in that range, this is the holder.
2) Why a porcelain wireholder instead of a metal or plastic one for service entrance wire?
Porcelain is used at every point where the wire touches the holder on the Topaz 999. That keeps the conductor sheathing from abrading against a hard metal edge as the service drop moves, and porcelain doesn't break down from sun and weather the way an exposed plastic part can. It's the reason this style has stayed standard on overhead service work.
3) Where does an SE wireholder go on an overhead service mast installation?
It mounts on the mast below the weatherhead and grips the service entrance conductors right before they enter the mast or service entrance cap. Its job is holding the wires in position and taking the strain off the entry point, so the drop isn't pulling directly on the cap. Standard on overhead service drop and weatherhead assemblies, residential and commercial.
4) Is the Topaz 999 wireholder sold individually or in a box?
It comes in a pack of 100, so it's a stocking quantity for an electrical contractor or distributor running multiple service jobs rather than a one-off part for a single mast.
5) Will the Topaz 999 work on a mast larger than 3 inches?
No. Three inches is the top of its adjustment range. For service masts above 3 inch you'll need a larger-capacity holder; this one won't close on the pipe correctly and shouldn't be forced.
