Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule describes the manner in which an

(1) No person may sell, offer for sale, or as
				a business install or cause to be installed a manufactured home tie-down system
				unless the system has been approved in writing by the manager and the original
				or duplicate original of such approval is prominently displayed at the location
				where the system is sold, offered for sale, or offered for
				installation.
(2) Applications for
				an approval shall be submitted to the manager and shall be executed by the
				owner or seller of the system on forms that shall be provided by the manager
				upon request. To be complete, the applications shall include:
(A) The name and address of the
				applicant;
(B) The name and address
				of all places of business which will be authorized by the applicant to sell or
				offer for sale, or install or offer to install the system for which the
				approval is sought;
(C) The name
				and address of the manufacturer of the system for which the approval is
				sought;
(D) A brief description of
				the legal organization of the manufacturer who will use the program, whether a
				Missouri corporation, foreign corporation, partnership, proprietorship, or
				other business organization;
(E) If
				manufacturer is a corporation, a Certificate of Good Standing from the
				secretary of state and a copy of the corporation's articles of incorporation
				and bylaws;
(F) If manufacturer
				does business under a fictitious name, a copy of the fictitious name
				registration filed with the secretary of state;
(G) If manufacturer has submitted the
				applicable information as set forth in subsections (2)(A)-(F) of this rule in a
				previous request for approval of manufacturing program, a statement that the
				information was previously submitted and remains unchanged;
(H) If the information in subsections
				(2)(A)-(F) above is not available, or not applicable, a statement as to the
				reason the information is not submitted. The manager, in consult with staff
				counsel, shall determine if the request for approval can be processed without
				the required information;
(I) A
				copy of the plans and specifications of the system for which the approval is
				sought.
1. Detailed drawings and the
				manufacturer's installation manual of each type of anchor system and for each
				type of component for which approval is sought must accompany the submittal.
A. Each drawing shall show model
				identification, all dimensions, types of welds or fastening, types of material,
				methods of securing strap, methods of attachment, orientation after
				installation in soil, direction(s) of applied load(s), and location of model
				number on the system and each component.
B. Each drawing shall bear the seal of a
				registered professional engineer, registered in the state of
				Missouri.
2. Each anchor
				system model must be tested and certified by an authorized testing agency to be
				in conformance with the following anchoring standards and accepted engineering
				practice:
A. Pullout tests shall be performed
				on three (3) samples of each anchor system model and the failure load for all
				three (3) tests must equal or exceed four thousand seven hundred twenty-five
				(4,725) pounds. The manager must certify that three (3) pull-out tests were
				performed on each anchor system model. The anchor shall be installed with the
				specified tie attached in a soil type for which the anchor is designed and
				pulled at an angle between forty degrees (40°) and fifty degrees (50°). The
				anchor will be approved for all soil test probe values at or above the soil
				test probe value in which the anchor is tested. The device shall be set up as
				required by the manufacturer's installation manual. The test report shall
				include a photograph or drawing of the anchor demonstrating it is fully set up
				as required. The load at failure and the type of failure shall be described.
				The anchoring system must be capable of meeting or exceeding the Zone 1 wind
				load requirements of the Federal Manufactured Home Construction and Safety
				Standards
				24 CFR section
				3280.306;
B. Failure and ultimate load capacity tests
				shall be performed on three (3) samples of each component part and must also be
				witnessed by the manager;
C.
				Laboratory destruction tests shall be performed on each anchor system model and
				the failure load must equal or exceed four thousand seven hundred twenty-five
				(4,725) pounds. These tests are needed to establish the required strengths of
				the components and component connections of an anchor.
3. The result from each test will indicate-
A. Point and mode of failure;
B. Force required for failure;
C. Description of test procedure;
D. Test equipment used.
4. The report of the results of the test in
				specified soil or rock groups will also include:
A. Method of installation;
B. Date of installation;
C. Date of test;
D. Soil profile description and soil test
				probe values.
5. The
				anchor manufacturer shall furnish and ship with each anchoring system,
				information on the types of soil in which the anchor has been tested and
				certified for installation, instructions on the method of installation, and
				procedure for identifying soil types. A copy of the manufacturer's installation
				manual must be submitted to the manager. The manager shall maintain a copy of
				the most recent revision of the manufacturer's installation manual.
6. The manager, upon receipt of new or
				additional information relating to the performance of any anchoring system, or
				a similar anchoring system, may request from the manufacturer of that anchoring
				system, additional testing or supplemental information;
(J) The location in this state where the
				system for which the approval is sought may be inspected by the manager;
				and
(K) An affidavit of the
				applicant or the applicant's agent if the applicant is a corporation, that the
				system for which the approval is sought will be manufactured in accordance with
				the plans and specifications submitted with the application and that as such it
