KEYSTONE Electronics has expanded its assortment of metal fan/finger guards to include 40mm and 4½" fan sizes.
Available from NPA , these guards, as do all other fan/finger guards in the Keystone line, meet the ‘quarter-inch UL plug gauge test’.
All Keystone's guards are manufactured from nickel, chrome plated, high quality carbon steel wire (C-1010) for strength, durability and attractive appearance.
Mechanical construction includes clean, strong, butt welds that exhibit a minimum of flash and consistent guard diameters for enhanced venting and maximum air flow.
The 40mm fan guard is manufactured with .055" diameter wire mounted through four .180" diameter eyes on 1.26" centres.
The 4½" fan guard is manufactured with .063" diameter wire and mounted through four .170" slotted openings on 4.13" centres.
Keystone Electronics Corporation offers a comprehensive line of interconnect hardware and components, as well as stamping, machining, and assembly services.
For modifications and special designs, Keystone also offers application-engineering services.
