For standard size new construction windows, usually 1 " under the nominal size of the window, which will allow 1/4" clearance all around. For example, for a 4030 XO window, make the RO 47" X 35". If you order a custom sized (heel dimension must be stated) window, the window will be the heel dimension ordered, so you will need to make the rough opening that size PLUS whatever clearance you wish, usually 1/4" all around.

The same size as your door. The door fits against the opening from the inside. The opening should be finished with an exterior perimeter seal or stop molding to seal against the elements. See similar questions...

Eight 8d common nails (See Figure 5) should be driven through the rectangular box (stair frame) into the rough frame to help hold the stair in place temporarily while positioning the stair as in step 4 of the instructions. When used properly, the size screws and nails suggested are best. See similar questions...

For all prehung units we REQUIRE that you provide us with your rough opening size. We will build the unit to fit the rough opening size that is provided. If this is for new construction, we normally add 2" to the height of the door and a total of 2" to the width of the door for a rough opening. This allows for the thickness of the jamb and leaves an extra 1/2? in width and height to square the unit. See similar questions...

For single doors, as a general rule, add 2" in width and 2-1/2" in height to the nominal door size for single doors. For instance, a standard 3/0 x 6/8 door would require a 38" x 82-1/2" rough opening. Pairs would require twice the nominal door width plus 2" as well as an additional 1/2" if there is an astragal ( between them. For example, a standard pair of 3/0 x 6/8 doors with an astragal would require a 74-1/2" x 82-1/2" rough opening. See similar questions...

The first step is to determine how much lumber you’ll dry in a year. Then figure your average drying time for each of the species you’ll be drying, and you can calculate the size kiln you need from there. For example: you need to dry 500,000 board feet of oak per year. Fresh off the saw, oak takes about 28-30 days to dry, so you’ll be able to do 12 loads in a year. Each load will need to be 42,000 board feet to give you the 500,000 board feet you need for the year. See similar questions...

The finished opening needs to be no less than two inches larger than whichever spiral staircase you choose. See similar questions...

Well, yes and no. New sediment filters can simply be installed, and you're done. As for carbon blocks, RO membranes, and DI resin, that's another story... Manufacturers recommend flushing new carbon block cartridges for at least 10 minutes before using the product water. Don't run the flush water through the rest of your system. Don't run flush water through other stages in your system. See similar questions...

Add ?" to sum of the nominal block sizes for both the height and width. Example: panel (using 8"x8" block) is four block wide and five block high. Rough opening needs to be 32-1/4" wide and 40-1/4" high. All mortar joints are 1/4" wide. Assumes a ?" mortar joint will be used. Multiply the number of glass blocks by the nominal size (4", 6", or 8"), and then add to that sum an extra 1/2". Apply this formula to determine both the width and height of the opening.

The general rule of thumb in aquarium keeping is to have no more that one inch of fish per gallon of water. Thus, if you had a twenty gallon tank (with no substrate or rocks to diminish the total water volume), you could have five 4-inch fish. This formula also assumes you will change 25% of the tank volume each week. See What is a water change? Why is it important? for more details. Realistically, however, you will need to consider the following factors when choosing what size tank to purchase: See similar questions...

Weight distributing is based on the amount of loaded tongue weight the trailer has. To purchase the correct size weight distributing hitch (WDH), you will need to first load the trailer as you would tow it down the road and then have the tongue weighed. You can weigh the trailer tongue by using a bathroom scale or taking it to your trailer dealer to have the tongue placed on a tongue scale. See similar questions...

While there is no such thing as "too much" power in a sound system, the system should be powerful enough to fill your room.

Our measurements are given in stem thickness first followed by internal diameter/length eg.: 1.6 x 12mm. Our rings are always measured internally. Straight and curved barbells are always measured between the balls. On curved barbells (eg., belly bars) measure the shortest distance between the balls along the inside of the curve. Inches to millimeters conversion (you my need to round up or down to the nearest whole mm as necessary): See similar questions...

In 4 foot (trough to crest) very steep waves as long as you have wind, she’ll reach and run with very little roll. (If anyone starts to turn a little green, get them out of the cabin, eyes focused on horizon, and don’t read, it should pass in a few minutes, if not gone too far). Close-hauled in 4 foot waves some spray will reach the cockpit but you can duck behind the raised pop-top (with dodger installed) to stay dry. See similar questions...

The overall dimensions of the mat must be accurate. B) The mat must be square. C) If the opening is not square with the outside of the mat the rectangle carriage must be squared up. D) If the opening is not the correct size the pressure foot must be adjusted for the proper mat thickness. E) If opposite borders are not the same the rule pointer(s) must adjusted. Caution: The adjustments must be done in the order listed above. See similar questions...

The smallest size we carry is 6 5/8. The largest size is 8. We will always carry core products in full size runs -- 6 5/8 through 8. Unfortunately, our vendors do not always make "Limited Edition" styles in full size runs, so they may be unavailable in smaller and/or larger sizes. We are always working with our vendors to expand size ranges offered. See similar questions...

You are made up of about 28 trillion cells, which consist of more than 70% water. These cells constantly cleanse, nourish and regenerate to keep you alive and healthy. You certainly don't want to tax them with the added burden of cleaning out the industrial and natural contaminants found in water today. Some people say, oh, but the minerals are important as well as making the water taste good. See similar questions...
