U-Clamp Series
U-Clamp 26
CNC-machined aluminium U-clamp for securing solar panels to mounting rails. The 26mm profile fits compact panel frames and mini-rail systems, providing a firm, vibration-resistant grip without deforming the panel edge.

U-Clamp Series
U-Clamp Series
U-Clamp 29
Mid-size 29mm U-clamp for standard residential and commercial panel frame profiles. Compatible with all SOLBE rail series, the 29mm body accommodates the most common panel frame heights across Indian installations.
U-Clamp Series
U-Clamp 34
Heavy-duty 34mm U-clamp for larger panel frames and high-load applications. Ideal for 400W–600W commercial modules where a deeper frame requires a wider clamp profile to distribute clamping force evenly.
Z-Clamp Series
Z-Clamp Series
Z-Clamp 29
Z-profile end clamp for 29mm panel frames. The angled Z-body locks the outermost panel to the rail end with a single-bolt fix, providing a clean weatherproof edge finish to every row.
Z-Clamp Series
Z-Clamp 34
Z-profile end clamp for 34mm panel frames, suited to larger commercial and bifacial modules. The wider Z-body maintains full bearing contact on deeper frame flanges for secure wind-load rated clamping.
Z-Clamp Series
Z-Clamp 39
Z-profile end clamp for 39mm deep panel frames, specified for heavy bifacial and framed thin-film modules. Machined from 6063-T5 billet for maximum stiffness under combined wind uplift and compression loading.
T-Nut Series
T-Nut Series
T-Nut 40
Sliding T-nut for the 40mm SOLBE rail slot. Drops into the channel from the end and slides to any position along the rail before locking — enabling tool-free repositioning of clamps and brackets during installation.
T-Nut Series
T-Nut 24
Compact T-nut for the 24mm mini-rail slot profile. Sized for SOLBE mini and mono rail systems, this small-format nut provides the same smooth slide-and-lock action as the standard 40mm version in tighter rail channels.
T-Nut Series
T-Nut 70
Heavy-duty 70mm T-nut for wide structural rail channels and GI purlin systems. The extended body spreads load across a larger bearing area, preventing pull-through under high uplift forces in exposed ground-mount locations.
Fasteners & Clamps
Fasteners
Rivet
Aluminium & steel blind rivets for permanent one-sided fixing on solar mounting structures. Used to fasten rail end caps, cable clip retainers and trim covers. The pull-mandrel breaks flush after setting — no back-side access required.
Fasteners
Spring Nut
Spring-loaded channel nut that inserts from the top of an open rail slot without access to the rail end. The spring retains the nut in position during assembly, allowing single-handed placement of brackets and clamps before final bolt tightening.
Fasteners
Allen Bolt
Stainless steel socket head (Allen) bolts supplied with all SOLBE AL clamp kits. The recessed hex drive resists cam-out under high torque, ensuring correct and consistent clamping force is achieved on every panel throughout the array.
Clamps & Brackets
L-Clamp
L-profile aluminium clamp for fixing mounting rails to roof purlins, rafters and structural members. The right-angle body transfers both vertical and lateral loads into the roof structure for a stable, code-compliant fixing point.
Fasteners
Flange Nut
Serrated flange nuts for structural solar connections where vibration loosening is a risk. The integrated serrated flange bites into the mating surface on tightening, acting as a built-in lock washer and maintaining clamp torque throughout the system life.
Fasteners
Spring Washer
Split spring washers for anti-loosening protection on all solar mounting fastener connections. The helical spring action maintains continuous tension in the bolt joint, compensating for thermal expansion and contraction cycles across India wide seasonal temperature range.
Fasteners
T-Bolt
Sliding T-head bolts for AL rail channels. Inserted from the rail end and positioned anywhere along the slot, the T-head rotates 90° to lock when tightened. Eliminates the need for pre-drilling or measuring fixing centres during installation.
Fasteners
Hex Bolt
Hot-dip galvanized hex head bolts for all structural GI frame connections — rafter joints, pile base plates, jointer splices and foot anchors. Full-thread and part-thread options available to suit shallow and deep structural connections.
Fasteners
SDS
Self-drilling screws (SDS) for direct fixing of AL rails and GI brackets to metal purlins and corrugated sheet roofs without pre-drilling. The hardened drill-point tip penetrates steel up to 6mm in a single pass, with a bonded EPDM washer for a weatherproof seal at each fixing.
Sealing & Weatherproofing
Sealing & Weatherproofing
EPDM Tape
Self-adhesive closed-cell EPDM foam tape for weatherproofing rail joints, roof hook bases and cable entry points. Conforms to irregular surfaces and maintains a watertight compression seal through India's full seasonal temperature swing — no cracking, shrinking or hardening over time.
