Description
Seamless Transition Cover Trim-Curved (MJ43) provides a minimalist, gently curved way to cover expansion and control joints in like flooring materials, where the joint needs bridging and supporting without drawing attention to itself. At 37mm wide, its narrow profile adequately covers and supports control joints of most common widths while still delivering excellent slip resistance across the covered joint.
Like its flat sibling (MJ42), the trim push-clicks onto a separate Multi-Height Base rather than being fixed directly, so the base can be matched to the actual depth of the joint — 5.5-9.2mm, 9.0-12.7mm or 12.0-15.7mm — before the curved cover trim clicks into place on top. That two-part system also makes future access to the joint straightforward, since the cover trim can be unclipped without disturbing the base.

Where to Use
- Expansion and control joints in like flooring materials
- Commercial and residential floors wanting a curved, tactile joint cover rather than a flat one
- Areas requiring good slip resistance across the joint line
How to Apply
- Measure the joint depth — select the Multi-Height Base range that matches the joint.
- Fix the base — install the Multi-Height Base into the joint per standard trim-fixing practice.
- Cut the cover trim to length — trim the 3.3m length to suit the run.
- Push-click the cover trim into place — fit the curved cover trim onto the installed base until it clicks securely.
Important Notes
- Confirm the correct Multi-Height Base range for the actual joint depth before ordering — an incorrect base height will affect fit and finish.
- The cover trim and base are a two-part system; both need to be specified together.
- Select the anodised finish to coordinate with the surrounding flooring and hardware.
< That two-part base-and-cover approach also means the same Multi-Height Base range serves both the flat (MJ42) and curved (MJ43) cover trims, so a supplier stocking one base range can offer either finished look without doubling up on inventory. Selecting between the flat and curved profile is ultimately a finish preference rather than a performance trade-off, since both share the same 37mm coverage width and slip-resistance rating. Ordering both the base and cover trim together in one purchase also avoids a mismatched delivery, since the two components are sold as separate line items that need to be specified in the correct combination.
Deciding between the curved MJ43 and the flat MJ42 profile often comes down to how the rest of the space is finished — a curved trim reads as a slightly softer, more tactile detail that suits interiors with other rounded or organic design elements, while the flat profile matches a more strictly linear, minimalist material palette. Neither is a better technical choice than the other; the decision is purely aesthetic once the correct Multi-Height Base has been selected for the joint depth.
