ATK002: Rig Extension

Add on arms to extend the AuthentiKit rig

  • Manufacturer: Allcam, DMP, see below for more
  • Product ID: MDM10, see below for more

With the ATK001 primary rig you mount either a flight stick from a low down position or a set of cockpit sidewall controls (throttle, trim wheels etc) at a higher up position, but you can’t do both as the rig comes with only one arm.

This rig extension allows you to add one or more extra arms. Three arms would, for example, allow you to support a flight stick and multiple cockpit wall controls which may be at significantly different heights.

Availability of these add-on arms has proven more difficult than all-in-one monitor stands, however we have so far found options for the UK, Germany/Europe and the USA with eBay meeting the needs of other regions.

United Kingdom

In the UK your best bet and so far only option is Allcam. Uniquely in the world they will sell individual arm sections of varying lengths as well as the monitor pole clamp by itself. This saves you paying a VESA bracket that won’t get used. You can buy either directly or via eBay. I would recommend buying two each of the 19cm or 26cm arms and one pole clamp. You may also wish to purchase an additional 19cm or 26cm arm to extend the flight stick mounting as a 3 section arm is the best option.


In the USA I have found one supplier for the standard 35mm pole. This is an eBay business micoco-64. If instead you are using a 1 7/8 pole then you have the option of an add on arm from EasyMountLCD.

Germany / Europe

In Germany and Europe you have the option of sourcing from Allcam in the UK and paying a little more for postage but without needing to buy parts you don’t need. You can also buy the longer 19cm or 26cm arms which are more useful. Alternatively DMP have a good option which may turn out cheaper.

Other Regions

I would recommend the Google image search technique if you’re struggling to find add on arms in other regions. Please let me know if/when you find any. Failing that Allcam is available via eBay in all regions as far as I’m aware and DMP ship to many but not all countries – try the link above to see if they can post to you.

If you are searching for equivalents remember to look for arms that look like the image below and with a pole clamp that fits a 35mm pole.

ATK001: Primary Rig

Primary rig for attaching AuthentiKit controls to a desk

  • Manufacturer: Allcam, Mount-It, see below for more
  • Product ID: MDM11S, MI-751, see below for more

The primary mounting system for AuthentiKit controls is a monitor stand, mounted in an inverted position as shown below. This picture shows only the flight stick attached however a second arm section at a higher level is used to mount cockpit wall based flight controls.

The monitor stand needs to be of the following specification:

  • Vertical pole should ideally have a diameter of 35mm (1 3/8 inch) although 1 7/8 inch can be supported in the US
  • The arm sections should have a cross-section of 30mm x 30mm and the design of each arm section should look like this with a jaw at one end and a hole at the other allowing the arm sections to be chained together

United Kingdom

The Allcam MDM11S available from the following suppliers. It has also been called the MDM11A and in fact any one arm MDM11 or MDM10 stand from Allcam should be fine. Please note that maximum desk thickness for this clamp is 43mm. If you need a deeper clamp see the link below for a replacement pole or see the other suppliers list.

Other brands/suppliers of an identical looking monitor stand are


In the USA the (apparently) exact equivalent to the MDM11S is the Mount-It MI-751 which comes with the less pretty but more functional deep desk clamp. They sell direct from their website or via a large number of resellers such as Amazon, Best Buy, Walmart, Newegg or more. I’d recommend Googling the model number and looking for the best price. Here are the two main options.

Another equivalent is the Siig CE-MTOP11-S1 which is identical to the Mount-It though a little more expensive. The Mount-It does seem to have sold out a lot in recent weeks though so the Siig may be your only option. You can get it from Amazon or various other outlets.

I have found no other models so far which exactly match the recommended 35mm (or 1 ⅜”) pole diameter and 30mm x 30mm arm cross-sections. However I have previously recommended the Mount-It MI-752 which has a 1 7/8″ pole and we have found add-on arms which are compatible with that. It is no longer the recommended option but for completeness this is the MI-752 from Mount-It. It costs more as it supports two arms however you can remove the arms from one side and use them to extend the other side.

Germany / Europe

In Germany a brand called Display Mount Pro sell a model DMP LCD352 or LCD352S either directly or via Amazon. You can also source the Allcam MDM11S in Europe via eBay. Another option is the Wasserman model.


In my Googling I found one other country where a different brand is selling a very similar model of monitor stand. This is the Rife brand sold via Amazon in India. The downside is that it has the 1 7/8″ pole and this has the downside that add-on arms for 1 7/8″ poles are hard to find outside the US. I include it here as sourcing options may change.

Other Regions

I hope to add to this sourcing page as others discover more options. A good way for you to find new options is to right click on the image top right of this post and do Google Image Search (assuming you’re in Chrome browser). For now the options you have are as follows:

  • Allcam appear to sell their MDM11S model via every eBay I have tested globally. The downside is the shipping as they post from the UK
  • The Mount-It MDM11S is also available via Amazon and eBay in many different countries but again postage could be pricey
  • You could also google the LCD 352
  • Please help me find more options and I’ll list them here
