Matrix Innovations Snag Arms
The standard snag arm is compatible with pretty much every alarm on the market, not only this we have made the base plate thin enough that it enables all of our indicator mounting brackets (and most other makes) to be used with it. We have also designed the base plate so that these can be used with the Delkim Nite lites, something that most others cannot do as they obscure the output socket. 2 versions are available, one with 5" arms for most alarms and one with 3.5" arms for use with ATT's.
Both the standard and deluxe Snag Arms feature 6mm solid uprights, we have steered clear of having balls on the tops of the arms like some others, not only are they unnecessary they cause your rod to “donk” against them when the rod is removed, after repeated use it can cause damage to polished blanks.
