SECTION 05 52 10

	ALUMINUM AND WOOD RAILINGS

*****  For over 30 years Rangine Corporation has provided the construction industry with high quality, functional, and distinctive shelving systems, counter support brackets, a handrail system, and other architectural specialties.  This guide specification section can be used to incorporate Rangine Corporation's Rakks System 700 Handrail System into a competitively bid construction project.  This system combines the strength of extruded aluminum with solid wood components to provide a sturdy, attractive, and cost effective solution for handrail and crashrail applications.

This guide can also be used to specify Rakks HR-303 and HR-203 Handrail Mounting Brackets.  These two-piece aluminum brackets are used for mounting solid wood handrails and crashrails.  These brackets can be specified in this section or the requirements for handrail brackets can be placed in another section where the wood rails are specified such as the following:

	Section 06 20 00 - Finish Carpentry
	Section 06 40 00 - Architectural Woodwork
	Section 06 43 00 - Wood Stairs and Railings

When inserted in another specification section such as those listed above, the various handrail bracket paragraphs of this guide will need to be inserted in the appropriate locations in either Part 1, 2, or 3 of the section specifying wood handrails and crashrails.

This specification section is organized by placing information in three standard parts:

	PART 1 - GENERAL		Describes administrative and procedural requirements.

	PART 2 - PRODUCTS		Describes materials, products, and accessories to be incorporated into the construction project.

	PART 3 - EXECUTION		Describes how the products will be installed at the construction site.

Throughout this product guide specification, references are made to other specification sections that might be contained in the project manual.  These references are presented as examples and coordination reminders.  Specification section numbers and titles are based on the 2004 MasterFormat published by the Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC).  For each project, these references will need to be revised to reflect actual sections being used.

Within the specification text, Imperial dimensions are presented first in brackets followed by System International Metric (SI) equivalents also in brackets.  Depending on project requirements, either the Imperial or the SI metric equivalents will need to be deleted.

The specifier will need to edit this product specification for a specific project to reflect the options and applications being used.  The guide section has been written so that most editing can be accomplished by deleting unnecessary requirements and options.  Depending on project requirements, some additional information will need to be added by the specifier.  Options are indicated by  [   ].  Notes to assist the specifier in selecting options and editing the specification guide are printed in bold and indicated with  *****.  For final editing, all brackets and notes will need to be deleted from the guide.

Other products manufactured by Rangine Corporation can be specified using the following specification guides:

	Section 10 56 10 - Aluminum Storage Shelving System
	Section 05 59 10 - Aluminum Support Brackets
