Wind Resistance and Training
The worst performance a pet door can have is when
it blows open in the wind. Then it's really leaking a lot of air!
The Endura flap pet door has been proven in a wind
tunnel to resist blowing open in winds in excess of 50 mph! In the
same comparison testing, two of the largest selling pet doors on the
market blew open at approximately 20 mph. (One was in the high
'teens', the other in the low 20's).
Nearly all customers have been satisfied with
Endura flap wind resistance "out of the box". However, magnet kits
are available to further increase wind resistance. Each size will
accept up to two additional magnet pairs across the bottom of the
flap which increases the magnet strength in that area by 50% to 300%
depending upon the size of the flap.
Some users would like the flap to be easier to push
open while training. The Endura flap design allows for
temporary elimination of magnets on the sides as well as across the
bottom.
When these magnets are removed, the Endura flap is
extremely easy to push and the floating threshold remains in the low
position. |
