Yes! If your MantelMount is installed correctly it will not only stay in the down position but you are able to stop it anywhere along the 24-30 inches of vertical travel path and swivel!If by chance your MantelMount is not staying in the down position, there is an easy fix. When your TV is not staying in the down position and it is at least 20 lbs for the MM340 and MM540 and 30 lbs for the MM700, then please adjust the long bolt inside the center arm to accommodate the weight of your TV.For the MM340 this is step 5.1 in the install manual.For The MM540 this is step 5.1 in the install manual.For The MM700 this is step 5.3 in the install manual.When you are adjusting the tension, you want the bolt to be traveling up towards your ceiling (the very top of the bolt is for TVs that are 20-30 lbs and the bottom of the bolt is for 90-125 lb TVs). Once you adjust the long bolt, your TV will now stay in any position!
