Cardas Patented Binding Post (CPBP) with long, rhodium over silver-plated binding posts

A single unit consists of a single knob, the top clamp, two posts, the base, and a 1/4-28 allen bolt. To install on a pair of speakers, you will need two units.

Designed as an OEM system, Cardas CPBP CS Binding Post can replace most stock binding posts. A single knob tightens both leads of the connected cable at the same time, without tools. The contact posts have no nuts or threads to over-tighten and strip.

Binding knobs can be custom-made in different materials, shapes, sizes, logos, or finishes.

The Cardas Patented Binding Post, designed as an OEM system, can replace most stock binding posts. The famous "one-handed binding post" offers a single knob that tightens both spades of the speaker cable at the same time. No tools are needed, and the contact posts have no nuts or threads to over-tighten or strip.

The speaker or amplifier's internal wiring is soldered to the inside of the post, achieving an extremely short signal path. Spades are covered by the top clamp, making the CPBP a CE-friendly part in Europe. A 1/4-28 Allen colt is supplied.

To accommodate different mounting surface thicknesses, the .25" diameter contact posts are available in two lengths. Short posts are .880" in total length (protruding .25" behind base). Long posts are 1.6" in total length (protruding 1" behind base). Posts are machined from high-purity billet copper. Posts are available in bar copper or plated with rhodium over silver.

A knurled plastic knob is standard. Other knobs are available, including bare aluminum (KBA), anodized aluminum (KAB), and an aluminum knob shaped like the Cardas Nautilus (KN). The anodized knob can be laser-engraved with a logo (KAE).

Installation

A single Allen bolt locks the binding post base to the chassis or cabinet. Raised bosses on the back of the base fit standard mounting holes, and the posts are then inserted into the base.

Using CPBP with Bananas

The CPBP is designed for use with spades; however, the top clamp can be modified to accommodate bananas by drilling a 4mm (or 5/32") hole in each of the two points indicated below.
