The INS-SP is a precision-machined spike receiver made from SUS303 stainless steel—a non-magnetic, highly rigid material with superior strength characteristics. Computer-controlled cutting ensures the dimensional accuracy needed for perfect spike seating without rattling or deformation.
The 130-degree concave angle accepts spikes ranging from acute (90°) to moderately obtuse (up to ~120°). A 2 mm deep, 8.8 mm diameter recess provides secure retention even under lateral impact, so your equipment stays firmly in place.
The semi-gloss hairline finish resists corrosion and blends discreetly into any system. Reversible design also allows use as a small standalone insulator. Dimensions: φ20 mm. Four pieces per set.
