When the header loads are heavy or the span is extra wide carpenters often use __ multiple king studs built-up headers LVL or glulam beams extra-large cripple studs

## Step 1<br />The problem is asking for the type of construction material or method that carpenters often use when the header loads are heavy or the span is extra wide. The options provided are multiple king studs, built-up headers, LVL or glulam beams, and extra-large cripple studs.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### **Multiple King Studs**<br />King studs are vertical framing members in a wall that support the header. While they are crucial in wall construction, they are not specifically designed to handle heavy loads or wide spans.<br /><br />### **Built-up Headers**<br />These are headers made by combining several pieces of lumber together. While they can be used for heavy loads, they are not the primary choice for wide spans.<br /><br />### **LVL or Glulam Beams**<br />Laminated veneer lumber (LVL) and glulam beams are engineered wood products made by bonding layers of wood together. They are known for their strength and are often used in situations requiring heavy loads or wide spans. They are commonly used in construction for their ability to bear significant weight and span large distances.<br /><br />### **Extra-large Cripple Studs**<br />Cripple studs are short studs used above or below an opening in a wall, like a window or door. They are not designed to handle heavy loads or wide spans.<br /><br />## Step 3<br />Based on the above analysis, the most appropriate choice for handling heavy loads or wide spans in carpentry is LVL or glulam beams.
