So setting a frame is easily and quickly by hand

Anyone who has ever built a frame, the setting of what I'm talking about. In the case of the conventional Zargenspannern must first through various wedges and pieces of wood, the gap between the frame and masonry filled to the tie holes so that the frame does not sag when tensioning.

This great device is not required. It simply adjusts the distance and secured the clamps on the frame. No falling down and no more bending. And best of all: Even before the assembly of the frame helps this tool. The frame can be transported and installed by one person alone.

I regret that I have this great invention not found much earlier.

From me there is therefore 5 points. Just a great thing !!

PS also the time required for mounting is considerably reduced.
