There's always been a great deal of variance in schutzhund a-frames. Doing this with 2x4s makes for a very heavy a-frame. Put a pair of anchors on each side for the chain you'll use to set the height of the a-frame. Buy pieces longer than you need so that you can take the a-frame low for young dogs or puppy agility practice. My next a-frame will also have handles built into each side for lifting.
Some clubs leave their wood rough, others seal, and some paint.
A few clubs have even painted their logos onto the sides. Alternately, you can sprinkle clean white playground sand over the sides just after painting, but this adds several steps as you wait for the paint to dry, brush off the excess, and paint again. You can also buy a small piece and roll it, setting it into the gap between at the hinge. All Rights Reserved. See shrink-wrap clause by viewing code.
