Camlock Connectors: How to Choose the Right Brand
The Major Camlock Connectors ManufacturersThere are several manufacturers of camlock connectors, with the most prominent ones being Leviton, Eaton (formerly Cooper Crouse-Hinds), Hubbell and Power Products LLC (aka Marinco). Over the years, the manufacturing locations of the vendors has changed, with Marinco and Leviton moving to Mexico, Hubbell to China and Eaton still manufacturing in the USA. All of the major manufacturers have warehouses on both coasts in the United States. Although there are many electrical distributors that are authorized to sell camlocks for all the manufacturers listed, very few actually stock the product. ATI Electrical Supply does, with over 500 sku’s and $100,000 of inventory.
Specification Similarities and Differences
Camlock Connectors have many different specifications, similarities and differences. The basic functionality of these manufacturers is the same, especially internally. A common question our support and sales team receive is whether all the different manufacturers products fit together. The answer is yes they do. The metallic connectors are all made of brass. The dimensions of the brass connectors are all built to specific tolerances and UL 1691, and they all latch by twisting the connector to lock them in place. Some manufacturers require 90 degree turns, others 120 or 180 degrees. The main differences between the various manufacturers are the boots and the retaining screw. All the manufacturers have a non-metallic, typically made of nylon, retaining screws that holds the boot in place. Through personal experience we have found the quality of the retaining screw can be a source of pain, as some manufacturers screws tend to bend or deform more than others. We have also experienced some retaining screws that break more easily than others. The main way each manufacturer distinguishes themselves is through ergonomically different boots that have the same basic shapes with a different grip.
As with most products of similar quality, service and price are what truly sets them apart. All the manufacturers price camlock connectors similarly, at a retail price of around $25 each. Choose a distribution partner that will provide the service and support you require, and no matter which manufacture you choose, you will have made the right choice.
