Professional Components. Flawless Integration.
Complete your exterior cladding project with RMC siding accessories. Whether you are looking for trim, corners, channels, or mounting blocks, RMC accessories are engineered to integrate seamlessly with RMC siding and soffit to deliver the professional results you expect.
Professional Vinyl Siding Accessories for Complete Installations
Professional exterior installations require comprehensive accessory components achieving clean transitions, proper weather sealing, and polished finished appearance. RMC siding accessories provide essential trim pieces, corner posts, channels, starter strips, mounting blocks, and specialty components for complete vinyl siding and soffit installations meeting professional standards.
Every RMC accessory is manufactured to the same quality standards as RMC vinyl siding and soffit. Accessories are engineered to integrate seamlessly with RMC panels, ensuring proper fit, correct function, and aesthetic coordination. Using RMC accessories with RMC siding assures installers of a complete system designed for reliable performance.
Corner Posts and Channels
Outside corners and inside corners provide clean transitions at building corners while protecting panel edges. Available in various lengths for different wall heights, corner posts feature properly engineered drainage channels preventing moisture accumulation. Color-matched posts blend seamlessly with siding while contrasting colors create distinctive architectural accents.
J-channel serves multiple functions including window/door trim, siding-to-soffit transitions, and edge finishing along roof lines and gable ends. Properly dimensioned channels accommodate panel edges securely while allowing thermal movement. F-channel provides secure soffit-to-wall transitions and professional fascia finishing.
Starter Strips and Mounting Solutions
Starter strips create essential foundation for proper first-course installation, establishing correct alignment, drainage plane, and secure bottom-course locking preventing wind blow-off. Robust nail hems with adequate slots ensure secure sheathing attachment.
Mounting blocks (J-blocks) provide recessed mounting surfaces for exterior lighting, outlets, hose bibs, and utility penetrations while maintaining proper water management. Channels around perimeter accept siding edges creating integrated weather seals eliminating separate flashing. Available in standard and jumbo sizes.
Trim and Flashing Components
Undersill trim (utility trim) secures panels at horizontal terminations where top-nailing isn't possible—below windows, at roof lines, and material transitions. Hooked profile locks panel perforations securely without nails. Finish trim provides clean edge finishing and creates decorative accent bands between courses or at profile/color transitions.
Drip cap (head flashing) installs above openings directing water away and preventing infiltration behind siding. Properly angled surfaces with drip edges break water surface tension ensuring water drops away from walls.
Color Coordination and Quality
RMC accessories available in colors coordinating with RMC siding lines for cohesive appearance. Select matching colors for seamless monochromatic installations or contrasting colors for distinctive architectural accents. Popular combinations include white trim with colored siding, coordinating neutrals, or bold contemporary contrasts.
RMC accessories are manufactured with quality vinyl formulations resisting weathering and maintaining dimensional stability through temperature extremes. Consistent extrusion ensures uniform dimensions and reliable performance. Complete product selection enables entire exterior installations using RMC components exclusively.
