100kg Ceiling Anchor Kit: Technical Installation Guide
Product Specifications
- Safe Working Load (SWL): 100kg per anchor plate.
- Plate Dimensions: 120mm (12cm) diameter for optimal load distribution.
- Substrate Compatibility: Concrete/Masonry & Structural Timber.
- Interface: Closed loop ring for carabiner or strap choke-hitch attachment.
The 100kg Anchor Kit functions as a high-stability interface for suspended loads. Its defining feature is the 120mm diameter plate, which is significantly wider than standard mounts. This technical design increases the surface area contact with the ceiling, reducing the "pull-through" pressure on the plasterboard or timber grain.
Professional Installation Protocols
1. Preparation & Layout
For Sensory Swings: Ideally, install two anchor points spaced 400mm – 500mm (40–50cm) apart. This spacing reduces pendulum collision risk while maintaining a comforting, linear swing motion.
For Hammock Chairs: A single central point is required. Ensure a clearance radius of at least 1.0 metre from walls or furniture.
2. Installation by Substrate
Method A: Structural Timber (Joists/Beams)
- Locate Centre: Use a stud finder to locate the exact centre of the ceiling joist (typically 90mm x 35mm or larger).
- Pilot Drilling: Mark the holes using the 120mm plate as a template. Drill pilot holes using a bit 2mm smaller than the screw shank.
- Fastening: Secure the plate using heavy-duty wood screws. Ensure the screw bites at least 50mm into the solid timber.
Method B: Concrete & Masonry (Slab/Brick)
- Drilling: Use a hammer drill with a masonry bit matching the diameter of the provided sleeve anchors.
- Clearance: Vacuum or blow out all concrete dust from the hole. Dust prevents the friction-lock from engaging.
- Expansion: Insert the sleeve anchor through the plate and into the hole. Tighten the nut to expand the sleeve against the concrete.

Frequently Asked Questions (FAQ)
No. Expansion bolts are engineered strictly for masonry (concrete/brick). If driven into wood, the expansion mechanism will split the beam, destroying its structural integrity. You must use wood screws.
The wider diameter distributes the user's weight over a larger area. This reduces the "crushing" force on plasterboard and provides a stable base against lateral movement.
Perform a safety check before every use. Ensure carabiners are closed and straps aren't frayed. Check bolt tightness monthly.
