When your Elapsed Time Indicator does not fit – this bracket does.
Many military Elapsed Time Indicators (ETIs) such as M7793/1, MS7793/5 and MS7793/6 are supplied without mounting flanges.
Why?
Because in real military platforms, one fixed flange never fits all.
That is exactly why the MS3345-2 mounting bracket exists.
It is not an accessory.
It is the mechanical interface that makes modern ETI installation possible.
The hidden challenge in military ETI installation
Military platforms rarely have identical panel cutouts.
Different aircraft, vehicles, shelters and ground stations all have:
-
Different panel thicknesses
-
Different hole patterns
-
Different depth allowances
-
Different retrofitted legacy layouts
Yet the ETI itself is standardized.
Without a flexible flange system, integrators are forced to:
-
Redesign panels
-
Machine custom adapters
-
Or worse – abandon a qualified ETI model
The MS3345-2 solves this problem elegantly.
What exactly is MS3345-2?
MS3345-2 is the standard military mounting flange for:
-
M7793/1
-
MS7793/5
-
MS7793/6
It converts a bare ETI body into a panel-mountable military unit.
According to the military mounting drawing (see ETI FLANGE, page 1),
the flange creates the correct:
-
Front panel interface
-
Screw alignment
-
Mechanical retention
while allowing adjustable depth positioning.
This is critical in:
-
Thin avionics panels
-
Thick armored panels
-
Stacked instrument clusters
Why modern programs separate ETI and flange
Today, most military procurement prefers:
-
One standard ETI body
-
Multiple mounting options
instead of locking the system to one mechanical layout.
By ordering the ETI without flange and selecting MS3345-2 separately, the integrator gets:
-
Installation flexibility
-
Easier retrofits
-
Better spares management
-
Less redesign risk
That is why M7793/1, MS7793/5 and MS7793/6 are normally delivered flange-less.
The MS3345-2 is what completes them.
Why MS3345-2 matters in real projects
If you are:
-
Replacing an obsolete ETI
-
Upgrading a cockpit panel
-
Integrating into a new platform
-
Matching an existing cutout
you will almost always need a mechanical adapter.
Without MS3345-2:
-
The ETI may electrically fit
-
But mechanically it will not install
This small metal part determines whether the entire indicator can be used.
The commercial advantage: immediate availability
In most military programs:
-
ETIs are ordered late
-
But installation is urgent
If the bracket is missing, the entire aircraft or vehicle waits.
MS3345-2 is available from Amironic stock for immediate delivery.
This means:
-
No line stoppage
-
No panel rework
-
No field improvisation
While ETIs themselves may have lead times, the mounting solution is already in your hands.
Summary
The MS3345-2 is not just a bracket.
It is the mechanical key that allows standard military ETIs to be installed across multiple platforms.
If you are using:
-
M7793/1
-
MS7793/5
-
MS7793/6
you need MS3345-2.
Without it – the indicator cannot be mounted.
With it – you get full mechanical compatibility and immediate project readiness.
