Junction Box With Rubber
The repositionable junction box support arm, comprising: a mounting flange mountable against a mounting surface, an enclosed junction arm extending outward from said mounting flange and said mounting surface, and an angled contacting edge; a luminaire housing having an angled mounting surface for removably attaching said luminaire against said support arm in a first orientation or a second orientation, wherein said support arm is rotated about 180° between said first orientation and said second orientation thereby positioning said flange in a horizontal position or a vertical position respectively.
The rubber composition comprising the EPDM rubber (ethylene-propylene-diene copolymer rubber) contained therein as its main component has been hitherto used in large quantities for a paper-feeling roller of OA equipments such as laser beam printers, electrostatic copying machines, and facsimiles; and automatic deposit/payment machines (ATM). This is because paper-feeding rollers of the OA equipments and the automatic deposit/payment machines comprising the rubber composition are highly resistant to wear and are not deteriorated fast by ozone which is generated in the OA equipments when they are operated to form images. That is, the rubber composition is highly resistant to the ozone. In order to obtain a high coefficient of friction in the friction between the paper-feeding roller comprising the rubber composition and paper, softening agent such as process oil is added to the EPDM rubber to reduce the hardness of the paper-feeding roller. Further, in order to improve the wear resistance of the paper feeding roller, oil-extended EPDM rubber is used to compose the rubber composition.
