Altronix SPACER6 1-Inch Aluminum Standoff Spacer 4-Pack
Overview
The Altronix SPACER6 is a 4-pack of 1-inch (25.4mm) female/female aluminum standoff spacers designed for mounting circuit boards securely inside Altronix enclosures and backplanes. If you are specifying or servicing Altronix power distribution hardware and need reliable board clearance without improvised solutions, these factory-matched spacers are the correct hardware for the job. Each standoff uses a 0.1875-inch (4.8mm) machine thread — the same thread pitch used throughout the Altronix hardware ecosystem — so you are not adapting mismatched fasteners that can strip over time or leave boards poorly supported.

Key Features
- 1-Inch (25.4mm) Standoff Height: delivers 1 inch of controlled vertical clearance between a circuit board and its mounting surface — enough to prevent contact with enclosure backplanes while keeping the overall stack compact inside tight Altronix cabinet builds.
- Female/Female Thread Configuration: both ends accept machine screws, so you can secure the board from above while the standoff itself threads down to the mounting surface below. No need for specialized tools — standard driver handles the 0.1875-inch machine thread on both ends.
- 0.1875-Inch (4.8mm) Machine Thread: this is a standardized thread pitch matched to Altronix enclosures and backplanes. Using the correct thread eliminates cross-threading risk and ensures you are not substituting hardware-store fasteners that may differ in pitch or material hardness.
- Aluminum Construction: aluminum standoffs resist corrosion better than zinc die-cast alternatives and are lighter than steel — a practical benefit when fully loaded enclosures already carry transformer weight. They will not add meaningful mass but will outlast the enclosure's service life in typical indoor security installations.
- Quantity of 4 Standoffs per Pack: most Altronix circuit boards use four-corner standoff mounting. A single SPACER6 pack covers one full board installation without needing to order multiple SKUs or split packs.
- Includes 8 × 5/16-Inch Screws: two screws per standoff — one for each female end — ship in the pack. You have what you need to complete the mount without a separate fastener order, which matters on service calls where cabinet time is limited.
- Designed for Altronix Enclosures and Backplanes: Altronix specifies these spacers as the correct mounting hardware across their enclosure and backplane range. Using matched hardware reduces warranty ambiguity and ensures the board sits at the correct height relative to terminal blocks and wiring channels. Pair with the appropriate security power supply enclosure for a complete installation.
Integration and Compatibility
The SPACER6 is documented by Altronix as suitable for mounting circuit boards in their enclosures and backplanes — the two product categories where board-to-backplane clearance is a routine installation requirement. The 0.1875-inch machine thread is a standard machine screw size (3/16-inch), so the standoffs are also compatible with any mounting surface drilled or tapped to that specification, not exclusively Altronix hardware. That said, if you are working outside an Altronix enclosure context, verify the mounting surface thread pitch before ordering. For integrators building out access control panels or alarm power distribution in Altronix enclosures, this is the specific hardware Altronix calls out for board support — no substitution guesswork required. When planning larger installations with multiple boards across several enclosures, note that each SPACER6 pack handles one board; order accordingly per enclosure count.

Frequently Asked Questions
Q: What thread size does the SPACER6 use?
A: The SPACER6 uses a 0.1875-inch (4.8mm) machine thread on both ends of each female/female standoff.
Q: How many standoffs and screws are included in the SPACER6 pack?
A: Each SPACER6 pack includes 4 aluminum standoffs and 8 machine screws — two screws per standoff, covering both the top and bottom female ends.
Q: What is the standoff height on the SPACER6?
A: Each standoff is 1 inch (25.4mm) in length, providing 1 inch of vertical clearance between the circuit board and the mounting surface.
Q: What material are the SPACER6 standoffs made from?
A: The standoffs are aluminum construction — corrosion-resistant and lighter than steel alternatives, suited for indoor security enclosure environments.
Q: Are the SPACER6 spacers compatible with non-Altronix enclosures?
A: The 0.1875-inch machine thread is a standard size, so these standoffs can fit any mounting surface tapped to that specification. However, Altronix specifically documents them for use with Altronix enclosures and backplanes. Verify thread compatibility before using in third-party hardware.
Q: How many SPACER6 packs do I need for a typical board installation?
A: One SPACER6 pack provides 4 standoffs, which covers standard four-corner circuit board mounting in a single enclosure. For multiple boards across multiple enclosures, plan one pack per board.
When you are installing circuit boards inside Altronix enclosures on a commercial access control or power distribution job, the SPACER6 is the hardware Altronix actually specifies for the task — 1-inch female/female aluminum standoffs with a 0.1875-inch machine thread, four per pack with eight screws included. It is a small line item that prevents a costly callback: boards resting directly on backplanes can short, vibrate, or shift under load, and field-improvised standoffs with mismatched thread pitch strip out and leave boards insecure.
Technical Highlights:
- 1-Inch (25.4mm) Standoff Height: provides consistent vertical clearance across all four mounting points — critical for keeping boards level and preventing contact with terminal strips or wiring runs routed behind the board.
- 0.1875-Inch Machine Thread: matches the thread pitch used in Altronix enclosures and backplanes, eliminating the risk of cross-threading that damages tapped holes in aluminum enclosure bodies.
- 8 Screws Included: two per standoff means you have the complete fastener set in one package — useful on service calls where rummaging for the right screw size costs time and risks leaving a board improperly secured.
Deployment Considerations:
- Order one SPACER6 pack per circuit board being mounted — the 4-standoff quantity maps directly to standard four-corner board layouts used throughout the Altronix enclosure lineup.
- These are indoor-rated hardware items; if your enclosure sees condensation or humidity cycles (e.g., exterior-mounted cabinets without climate control), confirm the full enclosure assembly has appropriate environmental sealing — the standoffs themselves do not provide environmental protection for the board.
The SPACER6 is the right call on any Altronix power distribution or access control panel build where you are populating a backplane with circuit boards and need factory-matched mounting hardware rather than substituting generic standoffs that may not align with Altronix's specified clearance heights.
