Open Wire Line Spacers

Price is per pack of ten (10) insulators.

***Need heavy duty spreaders? Click here***

Laser cut from acrylic, our open wire line insulators are easy to use. Their unique design holds the wire firmly and makes them so easy to fit.  The supplied insulators will be cut from clear (transparent) acrylic - a material selected for its excellent RF insulation properties. They have been designed for use with our lightweight antenna wire. Line spacing 27.5mm. Making low-loss ladder line is so easy!

We recommend a spacing between the insulators of about 50 cm for feeders that are held under tension. For other feeder configurations you may need the insulators closer together.


1) When attaching the insulators, the feedline must sit in the engraved groove for optimum performance

2) We do not recommend these insulators for use with wires other than our own lightweight wires. These insulators are not suitable for our heavy duty wire or the DX-Wire Ultralight UL wire.

    Brilliant design

    These spacers are brilliant, have used home made spacers in the past, but recommend these as they are just the job for making one's own feeder line. Easy to use and they keep the feeder ok. will use again when required.

    Excellent Open Wire Line Spacers

    Posted by Mike, MØMTJ on 28th Oct 2013

    Brilliantly conceived and superbly executed. Make your own low loss, almost invisible ladder line feeder. Easy to use and really does have a low visual impact. Impressive.
