INTERLOCKING

PIN SYSTEM

WHY PINS?

Pins matter because you care about…

Performance

Keystone interlocking pin system adds strength and structural integrity to a retaining wall far superior to that of a rear lip system. Keystone

interlocking pins are designed to provide the best wall performance – they ensure the wall unit is installed in alignment and maintains alignment

and stability for years to come.

Installation

Allowing for secure installation with ease, Keystone interlocking pins take the question out of proper block placement, reducing time

and improving your installation experience. Keystone pins easily slide into the pin channels of Keystone 2-PC Country Manor® and the

front cores of the Insignia™ wall units; securing them in place. (See product speciﬁc installation instructions for additional details.)

No Maintenance

Keystone interlocking pins are weatherproof, allowing the wall to withstand the freeze-thaw process, and other weather challenges.

Savings

Using Keystone interlocking pins saves you time and money. Keystone pins reduce the cost of concrete adhesive and simplify the

installation process. Projects using Keystone pins require little, to no, repair over their lifetime.

Try the Keystone interlocking pin system with your next Keystone wall project

and see what a big difference these little pins can make.
