Niigata Seiki Launches "TMD Rack Gauge RGSQ-TMD" for Cable Rack Connection Marking with a Single Gauge

Niigata Seiki Co., Ltd. (Headquarters: Sanjo City, Niigata Prefecture, Representative Director: Toshiyuki Igarashi), a precision measuring instrument manufacturer, has developed the new product "TMD Rack Gauge" for the electrical construction industry in collaboration with TomiDen Co., Ltd. (Headquarters: Takasaki City, Gunma Prefecture, Representative Director: Takahiro Tomizawa), and began sales in April 2026. This product is a specialized marking guide that allows for cutting and drilling marking at the connection points of Negurosu Denko cable racks (SR type and QR type) to be completed with a single gauge. It consolidates the work that traditionally required two types of joint fittings to be fitted on-site into a single specialized tool, contributing to improved construction efficiency at electrical work sites. ■ Main Uses Marking for cutting and drilling at connection points of cable racks (SR type and QR type) Electrical wiring work in factories, plants, commercial facilities, office buildings, etc. ■ Development Background In electrical construction sites, two types of Negurosu Denko cable racks, SR type and QR type, are widely used in a mixed manner. Since each requires different joint fittings, the traditional method for workers was to carry two SR and QR fittings and perform marking on-site. The complexity of carrying "two tools" and the hassle of transportation were identified as challenges. Upon receiving a development request from TomiDen Co., Ltd., Niigata Seiki began developing a specialized gauge to solve this problem. TMD Rack Gauge RGSQ-TMD: Completes marking for two types of Negurosu Denko cable racks, SR/QR, with a single gauge. ■ Product Features 【1】Supports both SR (main girder height 70mm) and QR (main girder height 100mm) cable racks with one tool. Traditionally, workers would apply SR and QR joint fittings to cable racks and mark the positions of the connecting bolt holes on-site. This product supports marking for connecting bolt holes of both SR type (main girder height 70mm) and QR type (main girder height 100mm) with a single tool. There is no need to carry both SR and QR fittings, and work can be completed with one jig. 【2】Demonstrates power in sites with many connection points, such as warehouses, commercial facilities, and buildings. It is particularly suitable for large-scale sites such as warehouses, commercial facilities, and office buildings where SR type and QR type are mixed and many connection points occur. It streamlines repetitive marking work and contributes to shortening construction time. 【3】Can be used for various purposes with scale markings. For positioning holes on main girders other than SR type and QR type, or for positioning hanging fittings, the scale integrated into the main body can be utilized. It supports a wide range of applications beyond the scope of a specialized gauge, such as positioning various components around cable racks, including hanging fittings. 【4】Thin design (9mm) for excellent portability, fits in a tool belt. With a thin design of only 9mm, it fits well in a tool belt and offers excellent portability on-site. The hassle of traditionally carrying multiple SR and QR joint fittings is greatly reduced, enabling light and agile on-site work. Thin design of 9mm, storable in a tool belt. ■ Product Specifications Product Name: TMD Rack Gauge Model: RGSQ-TMD Measurement Range: 0-160mm (1mm pitch) Compatible Models: Negurosu Denko cable racks SR type / QR type Body Size: W85×H166×D9mm Body Weight: 118g Body Material: Stainless steel Country of Manufacture: Japan (Manufactured at Niigata Seiki's own factory) JAN Code: 4975846669048 Standard Retail Price: ￥5,720 (tax included) Release Date: April 2026 Sales Channels: Electrical material wholesalers, electrical construction material retailers, hardware stores, pro shops, home centers, EC malls Target Users: Electrical contractors Product Page URL: https://www.niigataseiki.co.jp/newproducts/special_rgsq-tmd/ ■ Intellectual Property Rights Type of Intellectual Property: Patent Application Status: Patent pending Application Number: 2026-6306 Application Date: January 17, 2026 Subject Technology: A marking gauge and method for freely marking bolt holes at the connection ends of adjacent cable racks, adaptable to two different types of bolt hole positions and shapes with a single component, when drilling such holes. 【About Niigata Seiki Co., Ltd.】 Niigata Seiki Co., Ltd. is a precision measuring tool manufacturer founded 66 years ago, with manufacturing, sales, and calibration of precision measuring tools as its main business.
