Weight capacity per bracket

Maybe I'm just missing this, but what weight does each bracket support? If a pergola were to be attached to the roof for example that's 26' long by 8' wide, is it 40 lbs. per bracket based on the description or is it more?

On the ARB 10 adjustable roof brackets I see 6 holes for attachment. How many screws and what type and size do you recomend per bracket?

Will the 490-3 drawer fit in the model 45 or 47 cabinet?

In the model 62 it appears that the 471-3 fits and also fits the 45 and 47. It would seem that 490-3 should also fit in all 3 cabinets
Asked by: Carlos

Does the ARB10-10 work with any size lumber?

Asked by: Smith
Wood walk platforms must be 1-1/2 inch nominal thickness and walk platform must extend beyond bracket platform support by no less than 6 inches and no more than 12 inches. Wood walk platforms must be clear, straight-grained wood, and be free of knots or defects. If the walk platform exceeds 10 ft, additional roof brackets much be placed every 8 ft.

Different types of ladders are designed to keep you safe and productive when climbing or standing. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.
Height is referring to the actual ladder height. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. The highest standing level is four rungs down from the top. The highest permitted standing level on a stepladder is two steps down from the top.

Reach height is the maximum reach assuming a 5’6” person with a vertical 12” reach.
Ladders are designed to safely hold up to a specific amount of weight. The Werner Performance System defines five different capacities using a color and star rating system. The Duty Rating is defined as the maximum safe load capacity of the ladder. A person’s fully clothed weight plus the weight of any tools and materials that are carried onto the ladder must be less than the load capacity.

Werner offers ladder made from fiberglass and aluminum. Each material has characteristics which make it best for certain applications, or one material may simply fit the personal preferences of the user. For example, if working around electricity users should select fiberglass products due to their non-conductive side rails.
