Stafix and SpeedRite are made by the same company, they have chosen to merge all products to the SpeedRite name. You may receive either brand at this time.
Another Stafix classic and quite possible the strongest wood post insulator available. HD sturdy claw design and no pinlocks to break. In a pull test this design is superior over pinlocks. Can be screwed, nailed, or stapled on with unique staple guides and positive hold.
