Gate Anatomy
The ARMA Gate is a Modular Aluminum Sliding Cantilever Gate System
We will break that down and look at how the ARMA System works below but first, let’s get familiar with the main gate components:
An ARMA Gate is composed of 1 Main Gate Post, 1 Cantilever Gate Post, 1 Latch Post, 1 Latch Assembly, 2 Roller Guide Assemblies, 2 Bearing Truck Assemblies and of course the Gate itself.
Modular– The EC131 is a commercial grade security barrier product that is delivered to your door and assembled on site, by you, with only a handful of commonly available tools. Gate segments are assembled in minutes with no lifting equipment required. Modular segments are then joined to each other using our ArmaSplice technology.

Aluminum – Every ARMA Gate is made from 6061 Aerospace Grade Aluminum. Our custom extrusions have been engineered to maximize strength, stiffness, durability and life expectancy. Coupled with Stainless Steel Hardware and high tensile cables, you can confidently undertake your responsibility to protect your family and property for as long as necessary.

Sliding Gate System – Every ARMA Gate rolls on 8 high precision, sealed deep groove ball bearings which are built onto precision machined bearing truck assemblies. Each truck is CNC machined in house, from solid billet 6061 Aerospace Grade Aluminum. There are no wheels or tracks on the ground, leaving your gate free to function in any environmental condition. Two Lower Roller Guide Assemblies ensure that your Gate alignment is stable and precise at all times.
Configuring The EC131 ARMA Gate
Step 1 – Finish
ARMA Gates can be delivered to your door in both mill finish Aluminum or black powder coated Aluminum. Both are durable and attractive. Custom powder coat colors can be supplied but are considered special order. Feel free to call to discuss.

Step 2 – Clear Opening
The number of ARMA Gate segments that you require will be determined by the length of the clear opening across which you would like your ARMA Gate to span. This clear opening length will roughly constitute 2/3 of your total ARMA Gate length with the remaining 1/3 acting as a counterbalance. The EC131 can span openings from 3′ to 22′.

Step 3 – Gate Height
Generally your ARMA Gate height will be specified to match your existing fence line or it can be incorporated into your perimeter security solution in any way you see fit. The height is measured from the the general grade line to the top of the Gate panel after installation. ARMA Gate comes in 4′, 5′, 6′, 7′ and 8′ standard heights.
Step 4 – Infill Style
Secure your assets with Chain Link Mesh, Ornamental Aluminum or Wood Picket infill.



Steps 5,6 and 7 – Gate Post and Latch Post Solutions
ARMA Gate can supply 3 1/2 ” round galvanized Steel posts that are completely modular and will ship with the rest of you gate order. As seen above, your Gate Hardware (Bearing Truck Assembly, Roller Guide Assembly, and Latch Assembly) will mount directly to these posts with no additional adapter components required. This is the post type that we recommend for most applications. Alternatively we can supply adapter kits that will allow you to mount the Gate Hardware to a verity of other post and flat wall types (see the specs below). Note: We do not supply or ship the square steel or wood posts but the adapter kits come with all the required fasteners to mount to your posts. The Flat Wall Kit comes with the adapter plate only as the anchors required will be unique to each flat wall installation and should be sourced locally to meet your specific situation.
