Weapon holder

Use
The Weapon Holder is a piece of machinery used by the Covenant for storing certain weapons, using either an anti-gravity or magnetic suspension to hold its cargo aloft. It is most often encountered in multiplayer levels holding the Energy Sword aloft, but can hold other weapons. It costs 3 Forge points and is available on every map.

Weapon Holders don't only hold weapons it can also hold the already open Gravity Lift, but it will only hold it side ways.

Trivia
In Halo: CE, all of the Weapon Holders were closed.

The Weapon Holders can stick to almost any surface, even on a tree branch on High Ground.

On Construct, if you place a gravity lift in a weapon holder and place it on a corner, all players walking around the corner will be thrust out into the air and killed.

In the released map packs, the Weapon Holder is usually used to make certain objects float that normally would fall down again. Objects usually held in the air by Weapon Holders are Active Grav Lifts, Fusion Coils, and some other small objects like radios, drums, and radio packs.
