Terminal Strips and Turret Boards

Terminal strips and turret boards sit in a quiet corner of the interconnect world, but anyone who has wired up a control panel, a tube amplifier, or a piece of military-grade equipment knows how much depends on them. Terminal strips, sometimes called barrier strips or terminal blocks in strip form, give you a row of screw or solder connections for joining wires cleanly and serviceably. Turret boards are insulating boards, usually phenolic or fiberglass, fitted with swaged turret lugs so components and wires can be soldered to raised posts; they remain the standard construction method for point-to-point wiring in guitar amps, vintage radio restoration, and some aerospace and defense assemblies where serviceability matters more than board density. Sub-types in this category range from single and double row barrier strips with different pitch sizes, to feed-through and European-style strips, to pre-populated turret boards and loose turret terminals for custom layouts. Buyers typically check a few practical things before committing: current and voltage ratings per position, pitch and mounting hole spacing, base material (phenolic holds up well to solder heat; some cheaper laminates do not), plating on the turrets or screws, and whether the part meets any MIL or UL requirements their build calls for. One honest trade-off here is price versus traceability. Turret lugs and barrier strips from no-name sources are cheap, but plating quality varies a lot, and for defense or audio work that inconsistency shows up as cold joints or corrosion a year later. Packaging matters too, since bulk-packed turrets tangle and scratch while tape or tray formats feed better in assembly. Lead times on US-made turret board hardware can stretch, so planning ahead pays. You can check live stock and request a quote on this category at icxing.com.
