Total Storage & Protection for Up to Two Guide Rail Squares

The Dual FoamPac Systainer Insert protects both your GRS-16 and GRS-16 PE guide rails at the same time!

Designed specifically for our newer (post-October 2017) GRS-16 and GRS-16 PE guide rail squares, our Dual FoamPac Insert enables storage of up to two guide rail squares in a single Systainer3 M 112! These inserts are also compatible with the GRS-16 PE K (Kreg) and GRS-16 PE D (DeWalt) guide rail squares.

Super protective Kaizen foam is computer designed and cut by CNC router, so these systainer inserts are guaranteed to fit your guide rail squares like a glove. The result is uncompromising protection for your precision tools. Kaizen foam not only protects your guide rails, but can also be easily further customized with the available Kaizen foam hot knife.

Note: These systainer foam inserts only fit into the Systainer3 M 112 and now-obsolete T-LOC Systainers; not the older Classic Systainers.

Note: These inserts are only compatible with the new style of GRS-16 and GRS-16 PE, ordered after October 13, 2017.

    Logical Purchase with the systainer

    Posted by Brandon White on 27th Feb 2023

    This is a great addon - a MUST addon - when you buy the systainer. I only gave it 4 stars because the overall insert doesn't fit quite like I thought it should to the systainer itself. However, this is still a MUCH better option than cutting a DIY foam insert to match all the pieces of the Guide Rail Square.
