  2. Furring - Wikipedia

    en.wikipedia.org/wiki/Furring

    Vertical, metal furring is applied to the wall to create a channel and receive the siding material. In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, [1] or to increase the beam of a wooden ship.

  3. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.

    8-inch (200 mm) hollow CMU (concrete masonry unit) with 1 + 1 ⁄ 2-inch (38 mm) wood furring, 1 + 1 ⁄ 2-inch fiberglass insulation and 1 ⁄ 2-inch (13 mm) drywall on each side [35] 55 Double layer of 1 ⁄ 2 -inch (13 mm) drywall on each side, on staggered wood stud wall, batt insulation in wall

  5. Foley catheter - Wikipedia

    en.wikipedia.org/wiki/Foley_catheter

    The most common sizes are 10 Fr to 28 Fr. 1 Fr is equivalent to 0.33 mm = .013" = 1/77" of diameter. Foley catheters are usually color coded by size with a solid color band at the external end of the balloon inflation tube, allowing for easy identification of the size. [ 7 ]

  6. Strut channel - Wikipedia

    en.wikipedia.org/wiki/Strut_channel

    Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.

  7. Preferred metric sizes - Wikipedia

    en.wikipedia.org/wiki/Preferred_metric_sizes

    A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
