JCP ETA Multiple-Use Drop-In Anchors, Lipped & Smooth
We supply JCP ETA multiple-use drop-in anchors from M8 to M12, in lipped and smooth patterns. This is one assessed product line for multiple-use fixings such as runs of suspended services: the lipped pattern (including 25mm and 30mm short-embedment versions) seats on the face of the hole so every anchor in a run sets at the same depth, while the smooth pattern sets conventionally with the punch. Listed by JCP for solid cracked and non-cracked concrete C20/25 to C50/60 with fire resistance loading.
Also known as: collared drop in, flanged drop in anchor, lipped drop in, multiple use drop in, redundant fixing anchor.

Related specificationsWhy choose a lipped drop-in over the standard pattern?
The lip means the anchor face sits flush with the concrete face on every fixing, whatever the hole depth - so a run of threaded-rod hangers all finish at the same level, and the anchor cannot slip deeper while being set. Standard drop-ins rely on the setting punch for depth control instead.
What are the short 25mm and 30mm versions for?
Reduced-thickness base material - the short-embedment sizes are listed by JCP for use including hollow-plank soffits where a full-depth anchor may not fit. Check the assessed range covers the base material before specifying.
What does 'multiple-use' mean on an anchor assessment?
It refers to fixings installed as a group - like a run of hangers carrying a service - where the system shares load between fixings. Assessments for multiple use reflect that redundancy. If your fixing acts alone, check whether the specification needs the standard ETA range instead.
