Learn more by watching our NLS 30003 | 25mm Half Saddle Zinc Plated 6.5mm Hole | 50 per Box video.
The NLS 30003 is a zinc-plated half saddle designed to mount 25mm electrical conduit to walls, poles, and structural surfaces. The 30003 uses a 6.5mm hole for M6 fasteners and is supplied as a box of 50 saddles. Reinforced to handle Australian weather and outdoor installation demands, the NLS 30003 fits trades working in switch rooms, on power poles, and across residential and commercial job sites.
Conduit mounting often becomes critical on renovation and new-build jobs where runs need to be run externally or across multiple surface types—timber, concrete, brick, and galvanised steel poles. The NLS 30003 stands up to the rigours of these applications without corrosion concerns. Electricians stock zinc-plated saddles for fast dispatch to jobsites and favour value-first options that perform reliably without premium pricing.
The NLS 30003 offers solid material thickness at 2mm, giving confidence on high-load runs or exposed installations. Bulk packaging (50 per box) suits contractors stocking multiple job sites or managing main-run conduit runs across larger premises. The saddle's straightforward design—no moving parts, no fittings required—makes it a go-to choice for fast installation and inventory management on the back of a truck.
The NLS 30003 is not suitable for embedded-in-concrete mounting (use conduit clamps designed for pour-in fixings), for submerged or permanently wet locations (use 316 stainless saddles instead), or for high-vibration environments such as plant rooms and machinery areas (use rubber-lined saddles or spring clips).

(30003)
The 30003 is designed for 25mm conduit. The saddle wraps around the outside of the pipe, so it suits standard electrical conduit sizes used in domestic and commercial installations.
The hole accommodates M6 metric fasteners — 6mm bolts, lag screws, or masonry anchors. Most electricians use a 6mm bolt with a penny washer and nut, or a 6mm lag screw into timber and masonry.
Yes. The zinc-plated finish resists salt air, UV exposure, and Australian weather conditions. It's widely used for power pole mounting, exterior wall runs, and exposed garden lighting circuits without degradation or corrosion.
The 30003 is 2mm thick metal, which provides rigidity for high-load conduit runs and confidence on exposed installations without flexing under tension.
No. The NLS 30003 is a surface-mounted half saddle, not designed for internal cable tray or enclosed duct systems. For those applications, use proprietary cable tray clamps or tray-mounted clips.
