KD frames with drywall returns are designed to be used in drywall construction using steel studs or wood studs.
KD frames are available with or without drywall returns. Install drywall board leaving rough opening as shown.Center head in rough opening.Retract compression anchors on jambs into the throat as far as they will go. Slip jamb tabs into head slots and pivot jambs into locked position.Locate removable spreader at frame base for opening width.Square base of frame and install base anchor screws into floor plate.Attach head to jambs using four #8 sheet metal screws in holes provided in top of head. (Required on all frames.) Screws provided with jambs.Square top of frame and tighten compression screws with Phillips screwdriver. Sizing of rough openings for double rabbet KD frames using 2" face material: Width: Door opening size plus 1½" to 2"Height: Door opening size plus ½" to 1½" We can accommodate other existing rough opening sizes, if your conditions are different than noted above. Available with or without drywall returns. Karpen Steel can provide labels on KD Door Frames:
Nominal Frames Size: 8'-0" x 10'-0" maxJamb Width: 4½" min, 14" maxJamb or Head Face: 2" min, 4" maxProfile: Single or Double Rabbet Knocked Down Borrowed Light Frames Karpen Steel can provide KD Borrowed Light frames as shown on drawingCUFP0031.pdf. These cannot be provided with a UL label. We feel however, that a better option is a 2-piece slip frame for windows. See web site page on 2-piece slip frames.Knocked Down Assembly with CompressionAnchorsKnocked down frame assembly installation instructions. Compression anchor details are shown on the drawing along with standard base strap anchors.cufm0006.pdfcufm0006.dwgOptional KD Base AnchorDrawing cufp0030 shows the optional KD base anchor consisting of holes in the bottom faces of the jamb legs. These cannot be used alone on UL Labeled frames unless the standard base strap anchors are also used.cufp0030.pdf 181 Reems Creek Rd., Weaverville, NC 28787 (828) 645-4821 • (800) 851-2131 fax (828) 645-3230 fax outside USA

Frames can be knocked down, set up and spot welded at miters, or set up and arc welded at miters and ground smooth. The 12 gauge frames are saw miter welded or saw butt end welded, corner construction only. They are available for either 1-3/8" (35) or 1-3/4" (44) thick doors. CURRIES frames are manufactured for all wall conditions such as masonry, steel stud, wood stud, and poured concrete. Identical profile jambs and heads 1" face through 2" face in 1/8" increments are now available KD, M, G and MK profile. Frame sizes are available to match door sizes, in any combination of singles or pairs.
Non-Standard width or height frames are available on special order. Frames shall be M Series as manufactured by CURRIES of Mason City, Iowa. Frames are to be fabricated of either cold-rolled or galvannealed steel (as specified) of either 18, 16, or 14 gauge. Joints are to be diemitered with integral tabs for reinforcement and interlocking of the jambs to the head. 12 gauge frames are saw miter or saw butt end corner construction. Frames shall be knock-down or set-up and welded. Frames shall be thoroughly cleaned and receive an iron phosphate treatment prior to receiving one coat of baked on prime paint. Frames are to be reinforced only for surface mounted hardware, with drilling and tapping to be done in the field by others. Metal plaster guards are to be provided for all mortise cutouts. Minimum requirements for hardware reinforcements are to be as follows: Hinge Reinforcing-7 gauge, Lock Strike Reinforcing-14 gauge conforming to template requirements and closer reinforcing-14 gauge.
CURRIES offers standard and custom anchor systems to meet almost any job conditions. Anchors are available loose or welded in.

The door, frame and hardware must work cohesively to provide security from not only people, but various intruders such as fire, noise, storms, radio waves and explosions. Protection from explosion requires high performance security. Blast openings are key in securing buildings for the gas & chemical industry, military, embassy and government buildings. Some hollow metal distributors will shy away from blast openings for fear of not knowing what type of products to supply. Other distributors feel this type of opening is too complicated and will not offer blast products. The key to providing the correct products for blast is to know the pertinent information required and getting that to the correct people. The first question is what blast standard you are dealing with.
Most specifications will reference UFC 4-010-01. This Unified Facilities Criteria (UFC) was established by the Department of Defense (DoD) as Minimum Antiterrorism Standards for Buildings. The latest version of the standard is UFC 4-010-01, 9 February 2012, change 1, 1 October 2013. The standard is a 111 page document covering the minimum test requirements and standards. The standard identified the performance level for the assembly, post blast. Since the standard does not identify the size of the blast or the distance the blast origin is from the assembly, the standard alone will not give you the details you need to provide the correct product for the opening. Most projects will reference this standard with few other details. The key details needed are: A Copy of the Specification with blast criteria details included is critical in determining the correct door construction required. The specification language will spell out the test standard and other details on blast size and standoff distance.
A well written specification will also list the blast pressure and impulse load, both of which can be determined from the explosive weight and standoff distance, though a number of blast door specifications do not contain this information. The specification might also reference “Level of Protection”, “Damage Category” or “Hazard Level”. All of this information helps determine the door construction needed to contain the blast pressure. A Detailed Take-off will provide the door size along with hardware. This information is needed to confirm the door construction provided will be correct. The Building Elevation provides the hand of the opening. It is very important to determine if the door is a seated (swings into the direction of the blast area) or unseated (swings away from the blast area) application. An opening that is seated has the advantage of using the frame to help support the door in a blast and does not require special hardware. In an unseated opening, the hardware is critical in keeping the opening secure because the frame only supports the door at the latch and hinge locations during a blast.
The Section Detail and Frame Anchorage show the wall construction. The frame anchors and wall substrate are essential in keeping the frame intact. The frame provider has calculations that show how much pressure a particular anchor can withstand in various wall types. Peak Pressure and Impulse Load is important for determining the door type needed to meet the particular building blast requirement. Both are calculated from the blast size (charge weight) and standoff distance (distance from the door to the blast origin). The blast size is referenced as Explosive Weight. The Explosive Weight is categorized as 1 or 2, with Explosive Weight 1 being a larger (vehicle type) explosive and Explosive Weight 2 a smaller (carried by a person) explosive charge. The standoff distance is the span in feet from where the explosive can go off in relation to the opening. The greater the standoff distance, the less force or pressure on the building or opening. The peak pressure is measured in Pounds per Square Inch (psi).
The Impulse Load is also measured in psi along with Milliseconds (ms). The impulse load is the duration (length) of the blast load on the building or opening times the blast load (pressure) divided by 2. The peak pressure and impulse load are calculated by an engineer based on size of the explosive and the standoff distance. Developing doors and frames that will stand up to the pressures needed to protect buildings from the force of an explosion is a challenging process. Independent test labs use a shock tube to test openings at predetermined blast pressures. Using the data from the shock tube test, engineers can calculate the maximum pressure an opening can withstand. When you have a project with blast requirements, consult your door manufacturer to help you get the information needed to quote and provide the correct products. After participating in a project or two, you will see it is not that difficult of a product to provide. If you have any questions on blast products feel free to leave a comment.
