Wall plug with collar for downpipe mounting Koelner/Rawlplug 10 x 200 mm

Wall plug with collar for downpipe mounting Koelner/Rawlplug 10 x 200 mm is a fixing dowel designed for anchoring pipe brackets, clamps and supports in masonry or concrete. The collar provides a stable stop during insertion and helps position the fastener flush with the mounting surface, making it suitable for both exterior and interior mounting where a durable mechanical hold is required.

Advantages

The dowel's 10 x 200 mm dimensions offer deep embedment for improved load distribution and resistance to pull-out forces. A molded collar simplifies alignment and prevents the plug from slipping into the hole during installation. Constructed from weather-resistant polymer, it is suitable for outdoor use and resists common environmental influences when used with appropriate metal fasteners. The design is compatible with standard drill bit sizes and common screw or bolt diameters for pipe supports.

Suitable for

• Mounting downpipes and rainwater systems to masonry or concrete walls
• Fixing pipe brackets, clamps and saddle supports
• Exterior and interior installations requiring robust mechanical anchorage
• Applications where a collar is needed to position the fastener flush with the surface

Key specifications

• Nominal diameter: 10 mm
• Length: 200 mm for deep anchoring
• Collared head for secure positioning
• Material: weather-resistant polymer suitable for outdoor use when paired with corrosion-resistant metal fasteners
• Suitable substrate: masonry and concrete

How to use

Drill a hole of the correct diameter and depth into masonry or concrete, ensuring the bore is clean and free of dust. Insert the collared wall plug until the collar sits flush against the mounting surface. Position the pipe bracket or clamp over the plug and drive the appropriate screw or bolt through the fitting into the dowel. Tighten to the required torque without over-torquing to avoid deforming the polymer plug. For best results, use fasteners with corrosion protection for exterior installations.

Usage recommendations

Verify substrate condition before installation and select a stainless or galvanized screw/bolt suitable for the applied loads and environmental exposure. For heavy loads or hollow substrates, consider alternative anchors or supplementary mechanical fixing methods. Follow local building codes for external rainwater and drainage installations.
