I want to attach my perch to my Eglu run, which size should I get?

The 1m (3ft) perch fits perfectly in the Eglu Cube Mk2, Eglu Go UP and Eglu Go runs. 

The 2m (6ft) perch can fit diagonally across the Eglu Pro run if you have a minimum length of a 3m/9ft run.

If you have an Eglu Cube Mk1 run, you will need to get the 2m (6ft) perch and either cut it to the correct length or position it at an angle.
