Reinforced Double Door

A wide door that locks

The Reinforced Double Door is a wide door for bases in ARK: Survival Evolved and ARK: Survival Ascended. The ARK Wiki counts it as the second double door available, and since it is wider than a standard Door, bigger things fit through. The game describes it as "A reinforced wooden door that provides entrance to structures. Can be locked for security."

Placing and locking it

It can only be set into a Double Doorframe. Once it is in place it can be locked or unlocked, which keeps outsiders out while members of your tribe still pass. Doors do not change insulation, the wiki adds: a house stays just as insulated with its door open, shut or missing altogether.

Engram and recipe

The engram unlocks at level 31 and costs 4 engram points. The door is crafted in the inventory in 5 seconds, giving 2.28 XP, from:

• 40 Stone
• 28 Wood or Fungal Wood
• 16 Thatch

Each door weighs 4, and a stack of 100 weighs 400. Loot is a second source: 44 crate types can contain it, for example the Genesis Blue, Cyan and Purple crates on Genesis Part 2.

What can break it

For damage it counts as a stone structure, and only the attackers below can hurt it. The wiki adds a percentage to some of them:

• Weapons and turrets: metal weapons (5%), the Tek Sword (about 218%), explosives (150%), the Ballista Turret (40%) and the Cannon (about 137%).
• Creatures: the Therizinosaur, with its headbutt only (about 2%), Dunkleosteus (15%), Arthropluera, Chalicotherium, Deathworm, Magmasaur, Managarmr and Roll Rat, plus alpha creatures (10%) and astral, corrupted and enraged creatures.
• Special cases: the DodoRex and Dodo Wyvern (300% each), bosses (10%), titans, and the Titanosaur and Defense Unit (about 462% each).

The Giganotosaurus (15%), the Tek Rifle (about 50%) and the Rock Elemental can also hurt stone, although they cannot damage auto turrets.
