How to Choose the Best 40-inch Extension Ladder (A Buying Guide)

  1. Determine the load limit of the weight capacity of the ladder.
  2. Check its weight limit versus your requirement. The load limit must take into account the weight of the person plus the tools that he’ll be carrying.
  3. Select the proper type of ladder. For instance, step ladders are mostly for indoor use while extension ladders are perfect for outdoor repairs.
  4. Estimate and measure the span that the ladder needs to reach and add 3 feet on top of that. Only use a ladder that has the right length for the job.
  5. The rungs of the ladder should be able to provide at least 7 inches of toe space.
  6. Choose the suitable material for your repair or project. Extension ladders can be made either of fiberglass or aluminum. Aluminum is lighter but fiberglass is more heavy-duty. 
  7. The base and upper sections of an extension ladder must overlap. So a 40-foot extension ladder won’t necessarily help you climb up to 40 feet. 
  8. For more balance, extension ladders must travel 2-3 feet above the roofline. Anything less than 1 foot can be dangerous.
